They were very informative when it came to toppings I chose. They made sure to let me know what had gluten in it and what they couldn't guaranty was gluten free.
They have very basic GF pizza, same stock frozen cardboard - like shells you get many places. Nice thought, but not anything particularly special. Too bad, their regular pizzas are great... It's a lot to ask a place to be GF and as good as regular, tho.
