The gluten free crust here is pretty good and I've eaten here several times without a reaction, but I do think there's probably some risk of cross contamination. I haven't gone back since the time I received a gluten pizza instead of the gluten free crust (luckily recognized it since I'd ordered from there before). It was busy and mistakes happen but that's a pretty big mistake, and was extra frustrating since I didn't realize until I'd brought the pizza home.
