They're pretty attentive to allergies and amending items on the menu, our group had people with several different food allergies. The waitress was great but there was a mix up in the kitchen and part of the oder was forgotten. One of the gf items was touching a non-gf one so just make sure to clarify seriousness of gf issues if that's a concern (a non-gf person in our group ate it so we weren't concerned - all other gf items were separate)
