I've been to Crust many times, but the other night, I needed to get only one pizza, and a gluten-free pizza at that. I ordered it and went to my local Crust to pick it up. The staff were extremely helpful, they knew who I was and what I ordered, and they had it all ready for me. Usually, it's a bit of a penalty to have to eat gluten-free pizza, but that pizza blew my mind. Completely. The gluten-free pizza from Crust almost totally cannot be distinguished from regular pizza crust. It's THAT good. Add in the fact that Crust uses the best toppings of any pizza place I know, and what you have is the best gluten-free pizza you'll ever have in the course of your lifetime.
Highly recommended!
