I ate here (gf pizza) and got sick after :(
I am a very sensitive celiac and have never been bothered by their pizza. Furthermore, Romeos has the BEST GF pizza around. Truly. I would highly recommend.
I've ordered pizza here about a gazillion times since becoming GF. Better than local competitors offering GF pizza, and I have not been sick once. If you are extremely sensitive, cross contamination would be a concern here, but staff are conscientious.
