Every city has its own culinary strengths that are the by-products of immigration and socio-economic trends. If you're in Buenos Aires, you're going to try Italian food, and if you're in London, you're going to eat Indian food. What about the North American cities though? Would you eat Malaysian food in Houston? Would you try Mexican food in Toronto? What is particularly good in the Bay Area that outshines other cities in that regard? I've heard that San Francisco is one of the best places to try Peruvian food in the United States (and possibly outside Peru). What else do you think is particularly strong in this area?
