Any tips/advice for someone going to their first game tomorrow?

I bought 2 tickets to game 1 tomorrow for my dad and I and neither of us have ever been to an Astros game. So far I know to wear orange to support the team but aside from that I don’t know what to expect. Is there any good areas to park to avoid break ins and Is there any food places you recommend to eat either at the park or some place before the game? Any help I’d appreciate!
