The garlic fries are pretty good at Oracle Park. Hot chocolate is also pretty popular by the 5th inning as the temperature drops. Because it's San Francisco, be prepared to pay more for all of the food and beverages than you would in Milwaukee. New Belgium just opened up a tap house near McCovey Cove - that might be a good spot to hit up prior to the game. There are also a number of bars and restaurants between King and Brannan streets just west of the ballpark. Regarding the park itself, there is a small Giants museum ("The Vault") filled with memorabilia at the right field entrance (the entrance on 3rd street along McCovey Cove) that is worth checking out. Walking along the main concourse towards the giant glove and Coca-Cola statues in left field might also be of interest because of the backdrop of the Bay. Prior to or after the game, you can also walk out on a well-lit pier immediately behind the stadium - you'll be able to get a good view of the Bay, and after dark a good view of the Bay Bridge lit up. Outside of the park there are a number of plaques and statues commemorating different Giants milestones and players - some of the plaques are embedded into the exterior walls of the stadium itself and others into the pavement. On the south side of McCovey cove, there used to be a walkway that had the names of every Giants player memorialized along a concrete wall, but they ripped it out when they started the Mission Rock development. Likewise, they took out the Willie McCovey statue and the children's ball diamond that were on the south side of McCovey Cove - I think they'll be replaced at some point in the future when construction is done. As others have mentioned, the seats in the upper deck provide beautiful sight lines, but it gets COLD - even on days where the highs are in the 70's or low 80's. I would recommend wearing pants and a jacket. During the most recent Brewers series my wife brought her winter coat, a scarf, gloves, and a blanket - and we were sitting in the 4th row on the field level. It gets even colder in the upper deck.
