Staying downtown there are lots of bars/options. I'd recommend Fat Head's, Piper Pub and Carson St Deli on the Southside and Proper downtown. I have not been downtown recently, but I am sure there are lots of other options. Looking at breweries Draii Laag, Brew Gentlemen and Roundabout are all closed on Mondays. Your best best is probably Voodoo, which is an easy drive if you hit the other places on the Southside.
Edit: Smallman Galley is close to downtown and would have a good selection of local brews and some great food.
