Looking for a good chinese place in either FiDi or Chinatown that has great food, but also a more formal or relaxed atmosphere. We are coming from our offices (not in suits, but nicely dressed) and don't want to compete with the crowds. Does R&G Lounge fit this bill? I just moved to SF a few months ago and I understand that R&G is terrific, but not certain of the atmosphere. Good food is paramount. Nothing touristy.
