There must be two or three dozen Asian restaurants with lunch specials in the $7.50-10.00 range on 7,8,9 avenue between 14th and 23rd Street. The variety includes Thai, Vietnamese, Chinese, Japanese as well as places that have pan-Asian menus, usually with a Thai focus. The Chinese places look grim, though you never know, but most of the others seem inviting. Does anyone make a practice of lunching Asian in this area? Can you recommend places to go to or to avoid? Authenticity not a high priority, nor is portion size--I'm looking for light, pleasant, tasty, safe lunching. And if one or two of these places are particularly nice in the evening, that's worth knowing too.
