A friend and I have been roaming the city in search of off-the-beaten path ethnic restaurants. So far, we've gone to Brooklyn for Yemeni food, the East Village for cous cous, the West Village for Portuguese and the LES for Italian. We've got plans to find another spot for tomorrow. There will be three of us, coming from the UWS, UES and the West Village so I'm looking for a centralized location if possible. One of us is a vegetarian. Any suggestions for a must-try dining experience? About $50/person, max? Thanks in advance!
