Lucky you!
I stayed at the Hilton Club in July & loved it. I didn't try the Halal cart but I was amazed at the lines late into the night. We had an early flight & there was still a long line @ 4:00am, so it must be good.
We ate breakfast every morning @ the concierge room for the timeshare & found it was sufficient. No hot items but bagels, muffins, fruit, coffee etc... In the evening they had drinks and very limited food.
I use broadwaybox.com for my tickets. I usually get 50% off through here & like that I can chose my seats & plan ahead & already have my tickets. On this trip, I saw Catch Me if You Can (which I highly recommend) & Baby Its You (poor story but good music) & paid around 90 for each for front row mezzanine seats. Also, paid this for Sister Act earlier in the year. I checked at TKTS booth for the Adams Family & their price was the same I could get on Broadway box but not as good of seats.
For food, one of my favorite spots in Trattoria Trecolori. It is near Times Square down one of the little side streets & is great Italian at a reasonable price. I think normal entrees (lasagna, chicken parm) are $16.00. They have a website you can check out, and you definitely need to make reservations as they are small & always booked. I like to go here before a show as it is only a short walk from most theaters.
