I've been to the Pizza Cellar only a few times, but their food has always been great. One time I went there with my friends, and the waitress didn't seem too nice, but that was only once. Of course, you have to try the pizza, but I think you should try the popcorn chicken, too! As with many businesses in Princeton, it is small and locally owned, but that just adds to the character. Try it sometime when you're in town!
