I can cook better at home. 3/9/2011

Decided to come to KO Prime for a nice dinner outing with my husband and was truly disappointed. The ambiance is nice, service was good, but the food was definitely mediocre. We ordered the Veal sweetbread which was quite tasty and a good start to the meal, so we were looking forward to our entrees. We ordered the pork special, braised short ribs, and side of mac n cheese. The pork was bland and tasteless, the short ribs were nice and tender, but also had no flavor or taste to it, and I can get better mac n cheese at KFC and Boston Market. That's not saying much since those are known chains. If you want a good mac n cheese, go to John Harvard's. Looking at the tables around us, everyone was happy with their orders and had ordered similar food. I suppose our taste buds aren't refined enough to appreciate the fine essences they cook with. PRO to our experience: the mini appetizer and soup that were a special compliment of the chef that day. Apparently they share these mini surprises with all their guests. Those were nice and tasty. We just wish we could say the same for our entrees. We won't be going back there. CONS: Overpriced entrees that had no flavor. more

Solid prime rib 7/25/2010

I went here with a bunch of friends to try the all-you-can-eat prime rib special. For $30, you can order as much prime rib as you want. From the outset, we told our server that we wanted the prime rib to keep coming. He promised us that he would take care of us, which he did for the most part. The prime rib itself is cut into small slices. So when you are finished with your first (after a couple of minutes), you will have to wait sometime to get another order. This can be annoying if you have somewhere to go after dinner or if you are really hungry. The prime rib is very good though. It's cooked medium-rare (very bloody) with a lot of au jus. I didn't try anything else on the menu, but this restaurant seemed to be pretty solid. Pros: All you can eat prime rib option Cons: Price in general more

Overpriced 3/23/2010

Restaurant week review: Like many places for restaurant week you just don't get a quality meal anymore. We ordered the steak frites (not restaurant week menu) and cod from the restuarant week menu. Both were fine, nothing special. The service was average at best. For the price, there are finer restuarants to visit. Pros: Wine list (expensive) Cons: expensive more

Best New Reastaurant in Town! 8/29/2008

KO Prime has done everything right! Great food and great service. Chef Jamie Bissonnette's take on a new high end steak house is fantastic. The steaks were cooked perfectly, the short rib mac and cheese is to die for and the mushrooms are the best in the city! Good thing i didn't listen to any of the reviews below, obviously they were done by people that either never eat out, never worked in a restaurant on have no taste buds. Pros: Food Cons: nothing more

Huge Disappointment!!! 4/16/2008

Never been more disappointed at a so called ""high end"" steak house. Sure, the place was pricey but we all new that and expected to get what we pay for. But boy, were we wrong. Went with a party of five to celebrate a birthday and none of us were impressed. Steak was dry and overcooked and when the waiter was informed, they brought out a little flashlight and hunched over my shoulder to examine it at our table...how LOW CLASS!! I mean I felt like I was getting a PAP smear at the table!! All the apetizers and side dishes were nothing fantastic, not to mention our rissotto was RAW with crunchy rice grain....Our lobster was also overcooked (tough and chewy). I mean, come on, does Mr. Ken Oringer have any clues what's going on at this place? I can't imagine he does, he should be EMBARASSED to have his name associated with this place!! Pros: ambience Cons: no clues how to cook their steaks more

Outstanding steak house, food lives up to its rep 3/17/2008

My husband took me there for my birthday and we had an absolutely fantastic meal! The room is beautiful and cosey with a mix of booths and tables. Knowing it was my birthday, the chef sent us out a few dishes on him... nice to know that someone paid attention when my husband told them it was my birthday! All the food was amazing and cooked to perfection... the one dish that I just cannot get out of my mind was this homemade sausage that had this french farmer's cheese melted inside of it... unbeleiveable! Have never had anything that tasted so incredible. Really good time. Pros: Great food and service Cons: A little pricey for an everyday place, techno music did not fit the atmosphere of the restaurant more

Everything and More 2/13/2008

If I followed all the negative and ""it was OK..But....."" reviews I have read and listened to about Ken Oringers latest venture, I and my partner would have missed out on what we both agreed was as near a perfect evening as one could have in a restaurant. From the moment we walked up the marbled stairs and were greeted by a most genuinely warm hostess, to the moment we savored the last sip of a most stupendous wine, the evening was flawless. Pros: Decor, wine list, food quality, service more

Waste of time and money 2/11/2008

My fiance and I went for dinner this past Saturday. We often go to Ruth's Chris or Mortons when we're in the mood for a good steak, but we decided to give this place a try. Unfortunately it was a bad decision. After being seated we asked the hostess to see the wine selections. When the waiter came over he handed me the menu and said ""wines by the glass are on the first page......but they are a bit on the pricey side"". I thought this was a very interesting comment, seeing as we were just about to spend over $300 on a dinner for two, not including a 20% tip, without batting an eye..... In my opinion, its not usually in your best interest as a waiter to offend your patrons before they've even spoken a word to you!... Moving on, the both of us decided on the filet, and ordered them medium rare and medium. Both filets came out medium well and to our surprise were saturated in a ridiculously salty marinade of what tasted like teriyaki sauce. The tast actually can be compared to bad homemade steak tips from someones backyard barbeque . They were sooooo salty and saturated that I had to swish water after every bite. I know that most restaurants will use salt and pepper or additional rubs but this was over the top. We ate only about a quarter of the steaks and finished off our apparently ""too expensive"" bottle of noir and asked for the check. The steak should be in no way compared to any of the top steakhouses in Boston (Ruth's Chris, Mortons, Grill23, Abe & Louies). We will not be returning. Pros: Nice ambience and lounge area Cons: Overcooked/over-marinated steak, not worth the price more

Just Pass On KO Prime 12/15/2007

Just arrived home from ko prime. It was easy to get a reservation. Should have known right there. The host was helpful and the valet was great. The service was not good. After we had our meals, c+ at best, we received the check. I noticed the glass of wine my wife has was 20$ dollars. Don't mind spending money when the food is great and the service is equal(neither) but the response from our waitress was disappointing. She showed my wife the menu and said ""it's right here hun!"" Wrong answer. We eat at other fine restaurants in the city, this is never going to be one again. Just Pass On This One!!! Pros: mushrooms,valet service Cons: salty steak,service,lack of experience more

Waste of Time and Money 12/2/2007

The wine list was quite nice, so if all you are interested in is wine, go for it. Although be careful, the wine we ordered was not the one served (they brought out the 2nd wine of the St. Estephe we ordered). The fois gras was excellent, by far the best appetizer offered from the ""Hot"" section. The service was appalling. The entrees were brought out sequentially, misplaced on the table, and two of the three had to be sent back because they were not cooked properly (med-well was a cool-pink center). When they were returned to the table, the sides which had been on the plate had been placed in the broiler with the steak, indicating they just threw the plate back in the oven, and overcooked the braised chard. The duck came back over seasoned. Pros: ambiance Cons: everything else more

Don't bring clients here! 11/16/2007

I agree with the previous review and had a very similar experience last night while dining with clients at KO Prime. The waiter was not very friendly or attentive. One of my guests had to wait about 10 minutes after everyone else in the party was served to be served his dinner. It's always awkward when everyone else has their hot dinners in front of them and one person does not. After his meal was finally served, we did not see our waiter until after we had all finished our meals. Another person in my group had asked for a medium steak. It was overcooked. When the waiter finally came over to our table and she told him, he seemed annoyed. He then brought a candle to the table to get a closer look and argued that it was not overcooked. In fact, it was medium just like she had requested. I have never been to a high end restaurant where a waiter argued with a guest to prove a point that he was right about how the steak was cooked and the guest was wrong. I will never bring clients here again. It was embarrassing. If you want to impress clients with a nice meal, there are a lot of other steak houses in Boston that give much better service and know how to cook steaks how the customers request. I would suggest going to Capital Grill or Grill 23 next time! more

AVOID AT ANY COST!! don't bring any of your clients unless you want to lose your deal!!! 11/15/2007

I've been wondering how come an average of 2.5 star reviews came up to be 4.5 in citysearch summary. That just doesn't add up. We have about 5 people giving this POS place lower than 3 and only 2 giving full 5-star (most likely paid by the restaurant) and the summary says 4.5 star... I think citysearch is not being honest here. What a scam!!!! Pros: Nice view, nice interior Cons: bad service, bad steak more

Decent but nothing exceptional 11/11/2007

Upon being greeted the maitre?d offered to check our coats; a nice touch. Seating was prompt and reservations appear to be a must on weekends. The noise level is fairly high providing a level of privacy should you be sitting close enough. The staff were helpful and the service was above average. Pros: Service, Food Cons: Ambience, Food more

Well worth the price 9/28/2007

The service was impeccable, knowledgeable and friendly. We just went for a drink and we ended up stay for a couple and trying some of the apps. The drinks were made to perfection. The Steak Tartare was incredible and the Crab Salad was also uber good (a 5 out of 5 for presentation and taste). The ambience was very nice. It definitely has a swanky feel to it. I would highly recommend it. more

Truly outstanding experience 7/9/2007

The restaurant that sits where Spire once was has a lot to live up to. KO Prime exceeds its predecessor in every way, and will surely meet with success. Pros: Inventive and perfectly executed menu, great location, fantastic service, awesome drinks Cons: High prices - but worth it. more
