Any suggestions for food along the #7 train in Queens?
Any preferences or types of food you are or are not interested in? What have you eaten before and liked?
A list that Eric did a couple of months ago is a start. Any place that he says is on Roosevelt and many of the others are reachable from the 7.
Sripraphai, a Thai place, is the only one that, assuming you like Thai food, is universally acclaimed.
Any others on Eric's list you are curious about ask away and folks will respond.
Another source of info I don't think anyone's mentioned yet is the article Jonathan Gold did in the May 2001 issue of 'Gourmet' magazine. Titled 'Ticket to the World,' it was a four-page article on exactly what you're asking about - taking the 7 train into Queens as a way of exploring all of the ethnic enclaves and cuisines that can be found along it's route. It's a great start to exploring this route if you can find a copy, though a few hours on this board will lead you to even more recommendations than Jonathan could fit into his article.
This may be too late for you (since I assume you were planning this for this past Monday), but might help anyone else planning a similar day of exploration.
