6th or 7th ave in the 20's
re: S. Benson
Le Singe Verte isn't bad either. French place on 18th and 7th. Very standard.
Also like the Portuguese place (used to be O Padeiro, cannot remember new name) on 19th and 6th.)
Cafeteria on 17th and 7th is attitude-rich, but efficient at lunch and food is surprisingly reasonable and service efficient (at lunch only, it is not good at dinner). Turkey burger is yummy.
Hana on 22 and 7 is a straightforward, decent sushi place. I would not recommend Monster Sushi (which is on 23 between 6 and 7).
Haven't tried Porters, a new steak restaurant that opened up on 22 and 7 (across the street) but it looks good.
If you are looking for cheaper food, the Portuguese place is reasonable for lunch. Another place I like is Manhattan Heroes on 27 and 7. Great takeout - try the black beans and rice with lovely platanos. Also lots of tables.
