They have delicious GF options(if you like pasta) and are incredibly understanding about substitutions. Two of my personal favorites are the GF Penne Alla Vodka(you can pay a bit extra to add broccoli and/or chicken) and their GF Ziti which I was able to request on multiple occasions. You need to ask and be aware of the GF pastas they have and if you want you can sub them into most of the pasta dishes.
I don’t know about how celiac friendly they are but I have never had an unpleasant reaction as a result of eating their GF pasta. They also offer meat dishes and non pasta sides. As well as pizza both GF and regular.
