If you have kids, head to the Stomper Fun Zone, named after the team mascot. You'll find activities like a batting cage, speed pitch game, and coin operated rides. The area closes after the 8th inning and Stomper visits during the 7th on weekend games. As for other unique features, there really aren't many aside from a few championship banners and retired numbers displayed
Food and Drink:
As for general concessions stands - there's not a lot that's impressive about the food selections offered. There is a Tri Tip BBQ sandwich that's pretty popular and found at Kinder's Ball Tip BBQ. If you're in a luxury box suite, however, you'll eat very well.
There are some sit-down areas worth checking out, especially before the game. The West Side Club, located behind Home Plate on the Club Concourse is a bar and dining area with nice variety. Another good spot to check out is the The Field Irish Pub near Section 119 which has a great selection of beers and food. The BBQ Terrace (one in left and right fields) is a great deal if you're with a group, and the cost is $50 for regular games and includes a pregame BBQ meal and a private, Lower Box seating area.
The beer selection is decent (you can find Kona Brewing Co, Blue Moon, Red Hook, Fat Tire, etc), however it was recently discovered that the only difference between getting a large beer and small beer was the price. Apparently, Aramark, the company responsible for food service at the park has fixed this "error."
We need a new stadium and in a better area. Please!!
The Park and Neighborhood:
First off, Oakland-Alameda County Coliseum was a perfectly fine name for a stadium. A lot of ballparks are now named after companies that purchase the naming rights and tickets sales have been in decline so it's understandable, and at least it's not Overstock.com Coliseum anymore, but O.co isn't exactly an ideal name. Good news is it might change soon so just wait it out.
Anyway, O.com Coliseum is right off I-880 and is one of the oldest ballparks in the country. They have pretty good promotions including Free Parking Tuesdays, $2 Ticket Wednesdays, and Free Hot Dog Thursdays, all in an attempt to raise attendance numbers.
As for the neighborhood surrounding the park, it isn't the nicest in Northern California. It's not exactly unsafe, but it does feel a little sketchy, being very industrial. Most fans tailgate and then head straight home after a game so there's not many places to go nearby pre or post game. There is a sports bar located within The Hilton Oakland Airport (found on our exterior map) and they offer a shuttle to the game.
The stadium is easily accessible to the BART, making it the most convenient way to get to the game. Get off at the Coliseum/Oakland Airport stop which is only a short hike from the park.
If you're going to drive, then we recommend using the stadium parking lots. It's around $17 and lots open 2.5 hours before game time. With almost 10,000 parking spots, be prepared to wait while trying to leave after the game is over.
There isn't much street parking available nearby. Some BART stations offer free parking and there are a handful of neighborhoods west of the Coliseum you can park at to take the train in. (Visit www.bart.gov for more info on public transportation)
