Tailgating question

I’m taking the family to the game on Sunday. I used to go frequently but once we had kids I started watching from home. Got a good deal on tickets and a blue lot parking pass and it seemed like a good time to let the kids get a taste for live NFL football. My question is about tailgating. 8 years ago I had a pretty a solid group of people we hung out with and partied. Things have changed. Are there any tailgate outfits that sell entry for food and sodas? I seem to remember a couple did this back in the older days but I’ve been away a long time. Just trying to find a spot for the kids to get some bbq and have some fun.
