Hello, I'm travelling from Europe and will be in NYC for 2 quick days. It looks as though I will be dining alone (I'm female, not sure if that makes any difference in terms of where I should go), and would prefer to eat at the bar. Based on what I've seen here, I've decided on Minetta Tavern and WD 50 for dinner (though I'd love to hear alternatives or reasons to go somewhere else), but am undecided about where to go for lunch. I definitely would opt for sushi one day, and a quick Mexican bite on the other. Any ideas for good sushi and Mexican places for lunch? Neighborhood is not a critical factor, though I'd prefer something below 42nd street for lunch - i.e., more downtown than up. Thanks a mil for the input!
