Their chicken sandwiches are fantastic! I had both the spicy and the regular this week. Both were every bit as good as Chick-fil-A and without the guilt of supporting racism and intolerance.
My wife had the Black and White shake. It's a chocolate and marshmallow sort of thing that's surprisingly good. IMO, get a spicy chicken sandwich and a small shake.
Only negative is that it can get pretty busy. The staff is on the ball though and even the long lines move pretty quickly.
