Thanks to everybody who advised me. This is an outline of what we ended up with; details later.
Arrived at hotel at 1:30pm. Sutton Place Hotel(thank you Mike R.) Since we had a 5:30pm dinner reservation, we decided just to get some pizza and walk around. Ranalli's had been suggested, but the one near the Sutton Place is closed. We went to Gino's on Rush. Then wandered a while, then dinner was at Chilpancingo. Then the show at the Goodman, then out with cast and crew to Peterino's for drinks and some light food. Sunday we slept in, my boyfriend didn't feel so great, so we ended up going to the Little Pancake House across the street, and skipped Thai. Walked around some more, had knishes at Ashkenaz Deli, window shopped, and got on the train at 2pm back to the airport.
I'm sorry we had such a brief visit, since there's so much I wanted to try...next time!
Will fill in reviews of meals later.
