I'm local in Prague and back in times I used to come here often. However, in the beginning of the…read moremonth (7.6) me and my friends had decided to come to M1 to celebrate a bday. Right on the entrance there was an extremely rude bouncer, who screwed our mood so much that we just turned and left for good. Service is better at the public toilets in the subway all around Prague than at this place. Moreover, not long before my friend had come there and lost her wallet, one of the staff found it and confirmed it on the phone but when she came to pick it up they just did not return it to her, commenting it "it was not yours". Apparently, there were a lot of the same guess black wallets with her documents inside lost that night.
Another friend was robed there.
Thus, if you want to be robed, be treated as a piece of something and pay for this, come to M1.
