I LOVE to eat, and I eat a lot of food from other cultures (in NorCal, there's really no excuse not to try any food you've always been interested in) I think my favorite is Vietnamese. They have great combinations (anything from Vietnamese egg rolls to clay pots to spicy squid...).
I also have had Greek, Indian, Thai, Ethiopian (and by extention, Eritrean), Cuban, Japanese (I enjoy good, "fresh" sushi and sashmi
) Nigerian, Brazilian (my boyfriend and I went to a restuarant in the Village where we had many Mojitos and some good food!), Carribean (another favorite). Of course the old standbys...Mexican, Chinese etc. I love Italian food too (especially pizzas with unusal toppings like shellfish). Most Americans have eaten some dish of most European cultures (English, German, French, etc.) so I won't include them.
