I've heard of those all you can eat sections but I wasn't sitting there, the game I saw in California last month was at angels stadium and I thought the food was great
(The game was better though, since the Sox won)
On the other hand, I saw a rays game a couple years back and the food was terrible, it probably just depends on the ballpark, I guess.
Although, sounds like you had a crappy deal, bad food while watching an even worse team play.
