I work for a travel company and normally get 2-3 hours every two weeks to spend in the city. I love to spend this time trying new restaurants, bars and enjoying some cool sights in the historic district. If you have any gems your willing to share, especially microbreweries I would really appreciate it!
Definitely try this place: VRBA - The Virtual Reality Bar . Friendly atmosphere with enthusiastic staff. They have craft beers and you can try full room virtual reality there.
Fabrika, right behind the gardens of presidential palace, has very good range of their brews and a good vibe every evening. Well recommended.
