My husband has celiac's and we have gone about five times. Let them know when you reserve and check in. They will bring the GF guest a special plate. It typically includes three kinds of cake, chocolate chip cookies, some fruit, one or two kinds of ice cream or sorbet, gf brownie...I can't remember it all but it's been awesome. Sometimes they also tell him the GF choices on the buffet or go through what they can put on the plate for him and let him customize it.
It's really great.
