Burgers, sandwichs, finger food, and of course the best subs in New Jersey. This is the place to go in Princeton if you have a late night craving. The staff can be curt but they're never rude. Plus, you won't mind their laconic nature once you've tried the food.
The subs and burgers are delicious and hefty. They're sure to satisfy any hunger. You'll never be shorted on fixings. Add to this the extra little touches such as great burger rolls or large serving of any sides you order and and you'll be sold on Hoagie Haven. Yeah, I realize the burger roll pitch may sound silly but too many burger places serve their stuff on cheap, white rolls. Finally, every order seems to end with the guy yelling at you "salt, peppa, kethup?" It seems to blend into one word. Whatever you say your food will be great.
Go to Hoagie Haven late on a weeknight and you're sure to see the place crowded with engineering students. (Whether this is good or not is up to you.) At one point Hoagie Haven tried to add a delivery service but they were unable to handle the demand from the University. For a late night snack in Princeton this is the place to go.
