I've made a couple return trips to Dina's, and it's become one of my favorites. The pizza and wings are just incredible: always delicious, never disappointing. There are some weird specialty pizzas (seafood, taco... pierogi?) and they're actually worthwhile! But the classic pepperoni is great too. The "house mild" wings are more savory and sweet than your usual crappy vinegar-and-cayenne sauce, definitely worth a try. Protip: Order your wings extra-crispy, especially if they're going to sit in sauce for more than a few minutes.
Service has always been very good. My last server gladly brought me a cold mug for my beer, others gave extra napkins or whatever else was needed. And they'll chat and joke with you if they're not too busy.
I recently discovered they allow parking in a lot across the street so that complaint is gone. Now the only possible issue is that they could run out of seats in the busiest hours.
