Casual early dinner between Met and Guggenheim
Looking for a non-burger casual spot I can bring my 6 year old daughter. Something i can pretend is somewhat healthy like Paninis, salads or upscale pizza.
The Metropolitan Museum of Art is on 5th Avenue and 84th. The Guggenheim is on 5th Avenue as well, and 89th. That's only 5 blocks between them, with very few restaurants actually on 5th Avenue. Are you willing to go a little out of your way and then backtrack?
The most convenient places are near Madison AV (1 block over). Cafe Grazie (84th east of Madison) would probably work; there's a Le Pain Quotidian on Mad (84th-85th); very informal, but Dean and Delucca might work (Mad and 85th); and the Wright restaurant at the Guggenheim (altho I haven't tried that one).
Not exactly in between, but if you visit either place, I would recommend Heidi's House.
Small backtrack option is Serafina on 79th/Madison. Decent pizza/pasta.
That area is oddly tough.
