Tropicana Field

Team: Tampa Bay Rays
Capacity: 31,042
Food Highlight: Rays Cuban Sandwich

The fixed roof seriously detracts from the ~feel~ of a baseball game: No view, no breeze, and there are lots of obstructed views. It's lacking pretty much everything that makes the sport great for fans, so sadly it takes the bottom seed.

O.co Coliseum

Team: Oakland Athletics
Capacity: 35,067
Food Highlight: A slice from West Side gastropub

It's pretty bold for a stadium that barely fits 35,000 to call itself a 'coliseum'. The concourses are super narrow, making the place extra claustrophobic, and an entire section of perfectly fine seating is covered in tarp and reserved for Raiders games.
