To sum up: authentic Bavarian restaurant located off the strip with huge beer and great food.
To elaborate: My very first trip here was for a friend's birthday extravaganza. My first thought when I walked in was BEER!!!! and lots of it. Now being a Bavarian place they don't offer light beer so don't even think about it. They offered Hefeweizen, Dunkel and a seasonal - which in this case was a dark wheat beer. If you're looking for large quantities of tasty libation this is the place to go - get the litre and be amazed at the size of the stein you get.
On to the food - if you like Bavarian (read: German) food, this is the place to be. I happen to be a fan, so I was in heaven and quite honestly was torn for a while. Oh the food was sooooooo good - you have GOT to freaking eat here if you like German food. Plus, the portions are HUGE! This is excellent drunk food - which probably says a lot about Germans...and the desserts look amazing. I was too full to try one though.
Bringing on the atmosphere - for all intents and purposes this place is an authentic Munich beer hall. They have family style long wooden tables and benches, there is a huge shelf along one wall loaded down with steins, and a guy comes in and plays live music and gets loads of audience interaction. This is a very enjoyable place to come and eat - it's a little pricey (look to spend at least $30 per person if you're drinking), but it's definitely worth it for tourists and locals alike. I can't wait till Oktoberfest to see this place come alive.
There are also spankings and contests. Be intrigued...
