Smoothie King in Frisco has some of the best-tasting smoothies, but be warned, they won't let you get whatever you want in a small kid's size! I tried, because their smallest adult size is 20 oz and always too much for me to drink, and they said no. So I left empty handed and missing my Caribbean Way or Immune Builder. I went to Sonic instead and there smoothie was a very good substitute. So, great smoothies and poor service is my review.
