Thanks everyone for the good advice. I've now got a much clearer picture of what the area has to offer, and can't wait to get started. So much to do & so little time to do it! First time in NYC so really looking forward to the trip. We've got a couple of high end restaurants lined up so we're mixing & matching a bit by eating cheaply on other days.

We want to spend some time eating our way through the food carts along Roosevelt Avenue in Jackson Heights. Is there a particular time or day that is best to go? Are they there all the time or just lunch time & evening? Are there just one or two or (as we have been led to believe) quite a number all selling different items? Finally what is the best stretch of road to walk along? We were planning to walk from 82nd st subway to 74th st. Oh - and what about little India? Any carts there?
Many thanks for any help recieved.
