I've been getting delivery from this store about twice a month since they started doing gluten-free-crust pizzas. In more than 200 orders, I counted only 4 mistakes, and 6 orders when the toppings were skimpy. The pizzas are always hot and delicious, and the toppings are usually generous.
I occasionally get the slightly-more expensive "create your own" gluten-free pizza from Pizza Hut as a change of pace, and while they taste great, they are less than half the weight (according to my kitchen scale) of the Domino's equivalent.
Don't get the wings, though! I don't know whether it's this store or Domino's in general, but the few times I tried wings they were mushy (really old or nearly all fat, not sure which),almost inedible.
