I was a bar manager for Red Robin for 3 years. I know that. Generally they shoo everybody out at 1:30-2:00am. Food service usually stops at 1:30 when last call is given.

Full food service for an hour after closing alcohol sales keeps folks there instead of heading to Denny's, where I also worked for 2 years. That's when I started carrying a gun, and it saved my life one evening. (Long story)

The biggest issue is that we are a "liquor control" state. I am sick and tired of being smothered by the warm embrace of my government. That, and people are assholes.
