I find Control Club to be one of the best club and terraces in Bucharest with really good music and atmosphere. It’s a great trendy place for unconventional youngsters, both locals and visitors, at a very central location. They have different halls where you can enjoy a DJ set or concerts, or just have a drink. On Tuesdays everything is at half price!
There is also a restaurant attached, Alt Shift, where you could get great food in a very pleasant atmosphere, but it’s best if you have made a reservation beforehand, otherwise it’s always full. (Check Alex’ Alt Shift article.)
During the summer, it has an amazing open garden where you can sip a cocktail and just enjoy the vibe.
