Always make a point to go here when in Las Vegas. Like beer and German food and the menu covers a lot of ground. There's an indoor (you wouldn't want to be outside) beer garden in the back part which is quieter and good for conversation. At the front is the large open beer hall where the oompa bands play and there's guest contests and singalongs. (Yah, seems silly at first but after a couple beers...). It can get pretty loud in there.
Only complaint (and has little to do with the establishment, I think?) is that sometimes it can get a bit too rowdy with some of the guests - we've seen fights happen a couple times we've been there. So sad people can't just have fun.
