The only bar I eat is quest. Love them and good numbers. Most are 170-200 calories and 20 grams protein. 1/2 a bar will hold me for a few hours plus they taste good, in my opinion. Vitamin shoppe carries a few flavors but I try to order mine off the internet. My favorite is peanut butter and jelly. A lot of people microwave them for 10-15 seconds for a soft, chewy cookie-like texture. I've never tried that.
Most other bars contain soy so I haven't tried them but oh yeah! comes up a lot as being good and pure protein. I have no clue about those.
Good luck finding one you like!!
