I've been to ATC many times and I have to say it's one of my go-to favorite bars in Lakewood. I like the fact that there's three rooms and each one is a different atmosphere. If you go in the main room there's usually a live band, booth seating and a long bar. Keep walking through and you'll get to the outside bar. In the summer this part is hoppin'. In the winter it's just a bunch of people smoking in an "outside" area (it's tarped off).. which I'm not a huge fan of because it stinks. In the summer the outside bar is my favorite though. Next to the outside bar is the second inside bar, this one usually has a DJ, and a big dance floor. There's always people dancing like idiots in there (cough cough me cough cough) and it's a fun time. I like to get drunk in the outside bar then go dance crazy in the second inside bar. Plus the bathrooms are in there so it's better.
The bathrooms are really annoying, only two stalls for all those people! Whoever designed that should probably be shot. Besides that, this place is great. Cheap drinks, good crowd (some douche bags but much better than going to downtown Cleveland West 6th let me tell you!)... There's usually a lot of cute guys here too.
Overall, this place is really fun, I've definitely had plenty of good nights here and forgotten to close my tab out quite a few times and had to do the walk of shame in the morning. Don't worry they don't judge you too much :)
