If you're coming into Little Rock we only have one Micro; Diamond Bear Brewery. IMO it's really good beer, just not great....yet, that is. They recently have made plans to move and upgrade the brewery. Soon they will have a restaurant attached on the North Little Rock side of the Arkansas River. They have free tours on the weekend and during the week they are always looking for help on the bottling line if you want to get your hands "beery". For the help, they pay in beer not $$.
We also have a couple of decent Brewpubs. Vino's has OK house beers but their seasonals are usually fantastic. Plus they have awesome pizza to boot. There is also a Bosco's here and of course a Flying Saucer which is gonna be the best place in LR to get a good variety of beers. 80...ish? on tap and probably another hundred in bottles.
