Like Pizza? Pompeii is the place to go. So many different options it's hard to choose which option you want. Can't choose? Go for a 50/50 pizza. You also get 3 different sizes to choose from, unless you want a gluten free pizza, then one size fits you.
As for the gluten free pizza, this place understands gluten free, so risk (while not zero) is as close as it gets without being completely and utterly gluten free.
Plenty of drink options too, both alcoholic and zero alcohol.
Best bit of advice, book ahead to guarantee seating options, otherwise you can order take out (get uber etc to pick it up, or pick it up yourself).
