Gyro is a good bet for late night snacks if you do not want the ordinary pizza or taco bell. My only advice would be to order it well before you are actually hungry because they do take their time delivering. They used to have a problem with incorrect orders and when that did happen we experienced rather rude responses when we called to report the issue. This problem seems to have resolved itself, or at least I hope it has.
I love their hot wings, they are hotter than a lot of wings and meaty. Their other wing sauces are worth a try as well. Recently I discovered that they use a rather divine BBQ sauce, it is tangy with the right balance of sweetness. That sauce is excellent with their chicken fingers, with are rather large and well done. Gyros are always a safe bet, they have good cucumber sauce. We often get cheeseburger foldovers and stromboli but you do run the risk of having some undercooked dough with those.
Best of all, they are dirt cheap. They have $5 deals for carry out and dine in that will actually fill you up. They also have a wide variety of specials and deals to get you more food for cheap.
