I went to Hofbräu (by Alexanderplatz) with my brother and his girlfriend when they were visiting Berlin. He went there on his last visit and likes the one in Munich and loves their beer. I don’t drink beer but I trust my brother on his advice. The atmosphere is really nice, there was a Bavarian group playing music, people were singing and dancing. Quite cool. The staff was very friendly.
The food was nothing exceptionnal but not bad, I had the käsespätzel, they were ok but the cheese wasn’t very strong, my brother had the Haxe and really liked it, his grilfriend had the grilled goat cheese and the apfelstrudel and was happy about it.
Although it is very touristy, it’s quite a nice place, but go there for the beer and the atmosphere rather than just the food.
