New York Pizza is the best place for food in Aspen. Its address is 409 E Hyman Ave, but it's tough to find since it's above the jewelry store. It's up a flight of stairs and you know it's last call when the line goes down the stairs and out into the street!
You get a HUGE slice of pizza, every flavor you can imagine, for only $2! This is the cheapest place in Aspen, cheaper than McDonald's. When I was at the Motherlode three years ago, we ate every lunch and dinner there because it was the only place we could afford.
Yes, it's cheap, but it is really good pizza. They make their own dough and use fresh ingredients and all kinds wonderful meats and vegetables. Add in a soda and you've got a meal. Whole families can eat there for only a few dollars. The place is small so it's always nice to get your slice and just walk back out to the pedestrian mall and eat at a bench. They're open until 2am.
