Mob Bar is good, but it could be great. Nice decor and atmosphere (monthly Steampunk events with live DJs too), but the bar staff need to get better. The bartenders are fine for run-of-the-mill drinks, but are absolutely lost with anything out of their comfort zone. e.g.: I asked for a gin gimlet and the bartender says "You want gin in that, right?" Good drink prices though.
Important tip: Mob Bar validates at the garage across the street.
