Do you miss Insert Coins? Has Millennium Fandom bar 86'd you? Then come on down to the Nerd. It's a nice mix of both.
Three bar itself is rather small, but the bartenders make it work. There are a ton of different rooms including a stage/ dance floor, a bowling alley (that is super cute btw) and the game room.
I thought the game room was super fun. Free Pool (not the best equipment, but it's free right?), video games, board games, and local art. The video game chairs are up high, so you can feel like a king when doing your thing.
It's located on the second floor of neonopolis, slightly hard to find.
