First Chargers Game

Going to my first Chargers game this n Monday with my boyfriend. We are wondering a couple of things: 1- Is it worth it to go to a tailgate, if so where should we go? 2- best way to get there? metro or pay for parking? 3- how is the food at the stadium? is it worth eating there?

Our whole trip to LA is for this game, we really want the full experience!!
