We've been to Rosi's in a large group on a Thursday. Theme of the night: Rockabilly. Interestingly…read moremany guests take this serious and came quiet nicely dressed up; also the bar staff fittet the theme well. Overall a nice place and good mood, music was more-or-less-rockabilly then, always accompanied by the matching 60s to 90s videos on screen :D
Nice central large bar. I wasn't so amused when I found out they charge more than what is shown in the drink list. Mentioning "hey, this drink is 4,90 in the list" was answered with a sulky "and it's 5,10 on the cash register". I doubt that this was part of the "Rock" theme and thus considered it to be "not my service level" then :-/
Kicker tables etc. are available, and so are (a bit more silent) separees, so overall: yeah, you can go there. Just I probably wouldn't go a second time...
