My friends and I were visiting the roof top festival event that took a place at the Manes restaurant terrace; Unfortunately, we had quite upset experience and had to leave the place very soon. Just as a feedback I would like to mention that the...queues to the bar were incredibly long and slow moving, we had to stand 30-40 minutes in a line to get a cocktail. That could be a sign to the service performance in general… Btw, the cocktail (aperol spritz) itself was of very a limited quality, that we even decided to share our opinion with the bar manager; actually he was kind enough to accept this point and exchange with a new one for free. The next drinks order went also not good as expected. We had to put a notice to a bar tender, that quality of our cocktails is impossible to enjoy, but his behavior and reaction were inappropriately rude, we have been told that today they are busy (that was quite obvious, but not enough excusing) and don’t have time to deal with our complain. Then the lady from the bar started in a very arrogant way to put some additional alcohol from the bottle to our drinks (that made those even more horrible) and after we asked her stop torturing these drinks, she demonstratively started to ignore us; that’s a very low way of serving the guests (in my humble opinion at least) and I feel really sorry that such an amazing place with a nice view and river side location is being now removed from my locations “to go” because of a bad customer experience we have had that evening.More
