Best entrance to the park ... CF bleacher entrance, no ramps to climb and it takes you straight into the bleachers for BP.
Best concession stand ... the garlic fries stand underneath the CF bleachers parallel to the port walk next to McCovey Cove. No lines at this stand. Plus, they have chicken tenders.
Best food item ... the ChaCha Bowl at Orlando Cepada's BBQ stand behind the CF bleachers. It tastes great and it fills you up! If you're lucky, Orlando will be there sometimes near the back. I've received his autograph twice from that location!
Best seat ... anywhere. Personally, I like the lower deck. Bleachers are great - close to concessions and the express restrooms!
Best place to catch a ball during BP ... the bleachers. It's important to know which visiting team is playing. The team that has a lot of sluggers will usually one-hop a ball into the CF bleachers (i.e. the Boston Red Sox) ... otherwise stay in the LF bleachers and wait for the rebound.
Best place to get an autograph ... in the stadium, wait near the bullpen areas (for the pitchers) or get near the dugout. Out of the stadium, the best place is at the airport, when the Giants return from a road trip. They use to arrive at an United Airlines gate, not sure if they still do. For the visiting team, wait outside near the visiting team's entrance (adjacent to the Dugout Store) - I got Jeff Bagwell's autograph last season from that spot.
Best place to go before or after the game ... 21st Amendment Brewery, Gordon Biersch and MoMo's - good drinks and plenty of Giant fans!
Best souvenir ... the Splashing Landing penny machine on the Arcade concourse. They change the visting team plate for each series. Only $0.26 cents!!
