Flyaway: I asked another FT'r this same question via email. He (TUDORCITY) was kind enough to give me some detailed info. Here are his recommmendations with a comment on the ones we tried:

Dallas BBQ (Times Square)This was great! Very crowded and I can see why. Cheap, good and plentiful. Plus, Tudocity recommends that you go for early bird specials.

Salmon River

Michaels Cafe (East side Italian)

An American Place (Tudorcity says best Idine in the city)

TGIF Times Square (We went there because we have teenagers who love Fridays)

JT's Grill (41st and Madison)

Frer Jacques and Madison Bistro for French (Madison and 37th ST)

Rossini's (38th and Park)

Heartland Brewery (several locations) We tried it and it was good.

We would have loved to have tried more but found we were usually eating on the run. Hope this helps!
