91 is less tickets than from a large straight...
I only heard about Dave and Buster's only recently around four years ago after reading a post about how someone was raking in hundreds of thousands of tickets from the place, and now I've gotten a chance to experience some of it firsthand. Lots of tickets from a full game that required five swipes, and a bit over 600 tickets total. I'll return again as I haven't completely used up all the chips on my card yet.
Prices: Overall when converted to money per game, the price is significantly more than what you would normally find at Boomer's, John's, etc. (which is 33c / 50c a coin respectively), but the ticket rewards (in most games) scale up appropriately. Of course the ticket price for prizes go up as well, but not by too much. (The ratio for coupons to chips is around 10:1 if you play decently and consistently get at least 40 tickets on certain machines during 1/2 price days).
Food: I also went here to try out some of the food, and they were better than some other places I've been to. Got some mac and cheese, was not disappointed.
