Located a little off the beaten track in the port area, Arena 3 might easily be one of the biggest clubs in the vicinity of Old Town. The music is bumping and the crowd seemed to be a mix of Estonians and Russian-Estonians with a healthy dose of non-locals as well. We found the atmosphere quite reasonable, the drinks prices affordable and the large, rooftop terrace to be quite a bonus - at least during the warmer months.
