They do a "buring ring" stuffed crust, which is basically the usual cheese stuffed crust, but also spicy. Possibly the best thing I've ever seen done with a pizza.
I used to loathe Dominoes, but they must have changed their recipe recently or something. Their deep dish is waaaaay better than I remembered it being.
That being said, I still prefer locally-owned places as their pizzas are just... well, they're better 9 times out of 10.
