Stopped in on a whim on a Saturday. Pepperoni slice was delicious, dough is cooked nicely and really thin.

The pizza was really delicious! The dough was tasty and the flavor was great. The bacon and the pepperoni were juicy and well-flavored. The service was excellent too. They also offer a comfortable environment for enjoying pizza.

I order from Pizza den pretty consistently for the princeton math club and we have honestly never been disappointed by both the quality of the food and also the service that this location delivers. great and friendly staff!! the store is also great to sit down and dine in - the bathrooms are clean and the tables are in pretty great shape.

Really excellent pizza. Crispy and with a ton of flavor. If you love NJ pizza, it is on par with De Lorenzo's, Pete and Eldas and, Vic's. Service was attentive. The space is tiny but, it doesn't matter. You can even buy it by the slice.

Pretty good pizZA, very reasonable priced and girl at the front was really nice. The sign has real small weird letters though so you gotta look out for it!

That's great to hear! Fresh pizza with sausage and pepperoni is indeed a classic and delicious combination. It's always a treat to enjoy a tasty pizza.

Great little pizza shop on Nassau in Princeton. I am a pepperoni pizza purist, and the pepperoni slice was very good! There are a few small tables inside the shop and a couple right outside in front too. The employees were nice and handled the lunch rush well. They were happy to see a few regulars pop in.

Glad we found this little gem My wife & I had shared their board specials, a fig salad & fig pizza both were tasty and made with fresh ingredients, which they certainly don't skimp on We're looking forward to our next visit

Every time I go to Princeton this shop is different! It's towards the end of the business area but is always busy. The shop was redone into a brightly lit more modern decor. Both the store and bathroom were very clean. You can order several different kinds of slices or a whole pie. Only a few tables are available inside and out. It seems like they do a booming take out business. I had a slice of plain pizza. It was tasty with a good sauce, crispy crust and a nice amount of cheese. The usual toppings are available. Salads are also available as well as water and soda.

Grabbed lunch from here today with a couple of friends and enjoyed my pizza! Pizza Den is a small restaurant located just off Nassau St., with a couple of tables for eating, a counter for ordering, and not much else. The ambiance inside feels cozy rather than claustrophobic, though, and all staff were friendly and proficient throughout. My friends and I ended up sharing the large Brooklyn Pie and it was pretty good! Not the absolute best pizza I've ever had, but it was prepared fresh (I had to wait ~5 minutes for it to cool down before I could eat!), the sauce was reasonably tangy and tasty, and the crust was high quality. Cost was reasonable, and the drink selection was decent (I ended up getting a cold green tea which hit the spot!). I could definitely see myself coming back here if in the area and craving some pizza.
