What would be the best sports bar close to the Arizona Inn to watch the NCAA championship on Monday night. I'd prefer a mature crowd, not college age with decent food and drinks.
Trident. It's right by the Arizona Inn, too. There will be few students, but it will be totally packed. 1702 is also near there, but it will be even more packed. I've been to both during the tournament, and you're standing if you're not there early. If you're willing to drive, you can try the Red Garter, on Speedway near Country Club. They will have a crowd, but they have a lot of space, so I would imagine it wouldn't be as full. There's also a Native New Yorker across the street from there. I've watched games at other locations before, and they also don't get insanely crowded.
Old Chicago just north of there on Campbell would be another good option.
