I don't find much on the R&C menu that appeals to me, but there are lots of good things to pick from at Biergarten. Plus the performers are fun.
The one thing that was a little strange for me the first time I went was that, as a party of two, we were seated with others since the tables seat something like 8-10 people. When we were seated there was another couple at the end of the table. We tried saying "hi" but they obviously wanted nothing to do with speaking with other people at their table. A little while later a fun group of middle-aged women showed up and it was much more enjoyable after that.
