I've ordered from Luigi's several times as it is the only pizza place on the UES that offers GF (except for Uno's of course). It's pretty good. They delivery pretty quickly. The other review wrote about fearing cross-contamination, but I haven't had any problem (and I have severe reactions to miniscule amounts of gluten). You can't order by the slice, but I am yet to find anyplace that sells GF pizza by the slice. All in all, not bad pizza. I've had better, but when I want pizza at home, I order from them.
