Midtown where? East? West?
I'd stay FAR away from chains like Olive Garden and far away from Times Square (and also from Dallas BBQ, as at least one of their outposts has been actually shut by the health dept. recently).
You're kind of by 8,000 restaurants in Midtown...
There's a Serafina in the Dream Hotel, on 55th & B'way, where is to go for breakfast or brunch, unless you go to a diner (if you go to the Stardust, which is touristy but fun [food is better at Serafinas] ask for Erin to be your waitress!).
Le Bonne Soup is a classic, traditional bistro, so everyone should be able to find stuff there, good prices, on 55th by 6th.
Pazza Notte is really good Italian, brick oven pizzas, pastas, not too spendy.
John's Pizza is the best in the City (and the world) but go to the John's on Bleeker, the original location, the original oven.
There's a Shun Lee on 55th and Lex, which is expensive, but excellent Chinese food. There's Peking Park on 40th which is fine, regular-priced Chinese. There's a Schezuan something over on 50something too, and China Regency is an old standby on 7th.
There are a billion diners, dunno where in Midtown you are so...
You might find the Waffles and dinges truck for breakfast, lunch or a snack on the go. Follow the smell of freshly-baked belgian waffles - or
check their daily location here.
