Watching UFC w/ non-drinkers?

Going to be in Vegas for a show at the Sphere this weekend. Saturday is the UFC fight and I'd like to watch it with my group, but a couple of them don't really drink. A lot of places have $75-$100 covers/minimums. Doesn't make sense for us if they aren't going to drink.

Was hoping to find something in between like a good casino bar where we can stand/sit around without having to pay a cover and go gamble as well. We're staying at the Rio but can go anywhere to watch the fight. Any recommendations?
