They have a few options: By the weight, buffet only, and buffet with full meats. All are good choices depending on how hungry you are or what your schedule is like.
I've found that I enjoy the straight-up buffet items like the meatballs, chicken salad, steamed beets, cornbread, etc. and can do these alone as a lunch when I am on the go.
Their fresh juices are amazing.
They changed their name recently to Spettus, by the way.
