A friend enlightened me to this place on Memorial Day. They were open...so that was a good start. I'm a sucker for good German food (but quick to be annoyed by German slop claiming to be good food).
The Goodness: They were open on Memorial Day, that's a good start. $5.50 0.5liter beers is another good starting point (I got a tasty hefeweizen myself). We both had one of their off menu specials, the Lamb Loin. It came out green beans that were mixed up and cooked with bacon and fried up and potatoes that appear to have been fried up in Parmesan cheese or something. They were all sitting in this tasty dark liquidy gravy next to this perfectly cooked and seasoned lamb loin. The lamb loin did require a knife to cut it up...but it was still very tender. Tender and tasty. I can't quite describe what it tasted like. It is kind of like a good roast, but better.
The Meh/Bad: While the barkeep/waitress was nice enough....we were pretty much the only people sitting at the bar. Having to wait about 10 minutes before seeing anyone was kind of blah. Add to that when my friend asks the lady if they have any "lunch specials" she rattles off their list of "specialties" (off-menu "specialties"). We were unaware that we had this much of a misunderstanding...until the bill came...then we were keenly aware. Not sure anything "on-menu" was that expensive. It cost each of us $30 for the meal and a beer ($5.50 for a half liter of good German beer is pretty good though).
Conclusion: This place is worth the visit. Authentic and good German food. You do have to suffer the service though....which maybe our experience was unusual...but it really could've been a lot better.
