Watch party ideas/giveaways

I kinda found myself hosting a watch party at a new sportsbar, seperate from the organized main group I've been a part of. Unclear how many people are going to show up to mine but I want to start off our first meet up strong and wanted to see what yalls experiences have been. I'm definitely hanging a Texans flag out front of the bar, need to see what I can work out with the owner about drink specials, in the main group we did free jello shots for every touchdown, raffles/giveaways the very end which were often donated stuff. Any suggestions of things yall liked or didn't like at watch parties?
