We've eaten at Old World a number of times, both just me and with my family, and used carry out as well, and it is our favorite spot to go as a family. First off, there is plenty of seating if we need to spread out because God forbid our teenage son sit at the same table as us. Second, the service is always excellent, quick drink refills, and any problems/issues can be fixed immediately. But of course, the real star of the show is the pizza. The sauce is very good, the "normal" crust is good, and the meat toppings are always flavorful. The two places Old World stands out are the gluten-free crust - which the other 3 people in my family think is the best in Tulsa (actual gluten free, not the cauliflower crust some places offer) and the cheese. The owner can explain the difference in what Old World uses, but it's obvious and it amplifies and compliments the other flavors, even if that's just the sauce. I also think it's reasonably priced for the quality I'm getting.
