Cinelli's has, by far, the best pizza in Durham. Sure, it's expensive, but I think this falls under the "you get what you pay for" category. The spices are great; the sauce is tasty but not overwhelming. The veggies are always fresh. The grandma pizza is my favorite, but they are all good.
We've also had non-pizza dinners here and it's pretty good as well. Can't go wrong with Cinellis.
