What a beer hall! Ive been here a few times and everyone who comes along always has an amazing time. The beers are huge and light's not an option so if you're going to order a beer be prepared to drink.
It sounds like lately the entertainment has mostly been a one-man band but I've seen a full band play here in the past. All the gals are wearing German Bar Maid outfits (which become a bit more revealing in the later hours in the evening versus coming in for lunch) which is definitely a sight to see and they'll give ya a shot of whatever liquor is available if you'll let one of them paddle your arse.
Decided to go with the Bavarian equivalent to Bangers and Mash (Sausage, Mashed Potatoes, and Sauerkraut rather than peas) which was delicious and considering how filling the beer was, just the right amount for me.
If you've got about $25/head and are debating whether to stop in, go. You'll have a great time.
They also have a private photographer offering photos for $15 and $20. If you have a digital camera, their frame isn't worth the $15, but if not, go for it.
