I've been temping in the West 40's, and have only found overpriced, tourist-driven dismal eating options. Did a search for mid-town Chowhound, but found mostly recs for East side.
Made the mistake of getting takeout from Dish of Salt (in my current office building). Terrible, flavorless fare. Only bonus in this area is getting Wagashi from Minamoto Kichuan (sp?) on 49th - in a pinch, I ate some of the bean paste treats for dinner yesterday I'm ashamed to say.
Anywhere one can get a reasonable, non-touristy meal? Takeout is preferred.
