A small, tidy stadium for the A's. Parking lot available (most recently for the 2012 season $5) across the street from the stadium with a walkway overpass to get people to and from the p-lot/stadium (handicap accessible). There's some shady seats available and plenty in the sun. Bring a jacket if you sit in the shade, can even get a bit chilly!
As for the food, the most important part of baseball, there didn't seem to be huge selection here. I think on one end there were some sort of chow mein available (weird) and then the main specialty seemed like the bratwursts and the hotdogs fresh off the bbq. Get the footlong dog! So delicious and probably the most worth it. I didn't try it but they also have fresh brewed ice cream! Anyway, get the dog!
