I picked up a couple of those on seat geek last time I went. I didn't even know they were special seats until I got my ticket scanned. I think we paid $ 60 for the pair (lower level), so that was an amazing deal.
The lower level seats are in a great location, perfect to see Coyote goals. Can't beat that angle. For food, it was not a super crowded game and we got there 5 minutes late, so we had no line. Each of you gets up to 4 items per visit, and you can come back however many times you want. The choices are pretty simple: coyote dog, nachos, popcorn, soda or small water bottle. Nothing fancy. We got 4 dogs, 2 nachos and 2 waters on our first visit, I think that would have been close to $ 40 full price. We went back to get more water as the game went on.
I thought it was great. I would absolutely do it again.
EDIT: just grabbed 2 of those for the Lighning game tomorrow, SeatGeek: $ 26 each all fees included, section 108, all you can eat. I hate weeknight game traffic, but who can pass on a such a steal?!
