I would say the US has some of the best restauraunts but the worst street food.

Living in DC, tell me another area that has authentic (yes AUTHENTIC) Chinese, Japanese, Ethiopian, Afgan, Peruvian, Austrian, Bolivian, Cuban, Egyptian, French, Italian, Greek, Guatemalan, Indian, Korean .... you get the idea. Just about the only thing we lack is decent Mexican food (mainly due to the fact that a majority of the Hispanics in DC aren't from Mexico).

Many of my friends from those respective countries tell me the food is just as good as back home. Like I said, we just have crappy street food (which is one of my favorite parts of traveling).

Mmm street food :-)
