Living in Brooklyn, I usually follow the outer-borough message board. However am currently attempting an inter-borough relationship and have found myself searching for casual date places in The City. Simple request: tasty authenitc(ish) Mexican food in Manhattan. Basically looking for dishes whose main flavor is something other than cheese and who don't feel the need to go for the Spring-Break-in-Cancun decor. Recs? Feel free to throw in your ideas for other cuisines and restaurants, btw - dating in NYC can get awfully expensive and I'm always on the lookout for interesting places to eat.
