First, please forgive me, but I am being incredibly lazy today and not searching first - it's been a bit of a week. I'm meeting a friend for lunch tomorrow, and would like to find a not too expensive place to have lunch and linger. My friend mentioned seeing at least one Vietnamese place around town, but lives in Poland these days and hasn't had a chance to try any local places on this visit. Open to all kinds of chow.
Also - bonus points for suggestions for used bookstores in the area (looking for cookbooks) - I'll have some time to kill after driving up from White Plains (driver's license renewal), before lunch.
