I'll be up in NYC in early January for some training and will be without my wife for most of my time. I'm looking for some recommendations for restaurants where a lone diner can fit in and enjoy good food. I'm looking for that place where I can sit back, people watch, enjoy a nice dinner, without feeling like the spotlights on me for dining alone. I'm not opposed to dining alone, have done it many times, but I know of some restaurants locally where the environment is ideal for lone diners. I'm open to any type of cuisine and staying in the Financial District, but of course willing to explore other parts of Manhattan. Thanks in advance.
