Beer O'Clock

One of the best beer pubs in the old town in Bucharest, they have all sorts of beers you won't easily find anywhere else in the city. They also support the local craft beer industry, I especially recommend the hop hooligans ones. :)

Cozy place with a local bar vibe. Huge selection of import beer. Its nice that although they don't have food, you can order pizza from the pizza place next door and they bring it to the table.

Good selection of craft beers, although some of the items on the menu were unavailable.

The place is quite small, which I appreciated, considering how noisy larger pubs can get.

The listed closing hours were 2AM but they usually close earlier and there was an instance where they refused to allow people in around 0:30AM claiming they already closed. That is unprofessional and I wouldn't recommend going here anytime near closing time.

Good selection of worldwide beers. A bit plain on the inside but the local Romanian brewery hop hooligans had some delicious cans. Would recommend to beer enthusiasts.

The owner is a bit gruff but don't let that decieve you - he has a heart of gold. Speaking of gold, his taps pour liquid gold of the highest quality and his fridges are full of bottles from all over the world. Definitely worth visiting if you're a beer buff.
