It's great that there is a soccer stadium in the Bay, but it has some issues. The seats make Southwest seem roomy and the floor level is only for luxury seats and suites. There is a great bar, though
The long bar at the end of the stadium is a great place to hang out and soak in the environment, be it pre-game or the game itself. Stadium is right sized and has great sight lines.
Know that certain food items like BBQ and carved sandwiches are in only a single concessions location. Use a map (or the phone app) to find what you want.
