This is one of my favorite stops when in NoDa--I always make sure to stop by when I'm in the area.
NoDa 101 is a very small, quirky and unique bar. When you walk in, the room is consumed by the giant bar in the middle. They have a small stage up front for some of the area's best karaoke. There are a couple of arcade games in the bar as well for entertainment...but truly the karaoke is the reason to go!
If you're looking for a bar that's always busy, this is not the place. I've gone in multiple times and been the only person other than the bartender. But at night, especially on the weekends, you can expect a good crowd looking to have fun!
