As I recall, about 60% of the menu can be made GF, but even better, this place seems to be aware of GF issues. The food isn't fancy, but is well-made. A very popular place. The inside area is very loud and busy -- so go to the courtyard in back, which is very pleasant when the weather allows. But I actually avoid this place because: 1) I was never into burgers much anyway; and 2) I can't stand to see my friends and family eating what look and smell like truly wonderful fries!
