It's open. The OP sausages are excellent and the smell of them with Sauerkraut is intoxicating even before the beers come out. I recommend getting your sausage in broth with potatoes are the pretzel bun is too hard to hold the sausage. maybe if you cut it lengthwise you could get it to hold inside but I could not.
The burger is a good value at $6, with hints of Special Sauce, iirc. it's been a while since I've had a fast food burger. I ordered it rare and it was medium rare. Generally, I thought the food was standout for the albeit low water benchmark of American beer hall food.
The beer list is good but they aren't numbered chronologically so you need to write down the name of your beer on your taster tray doily, not just the number. Especially after a couple beers, you'll have the darndest time finding which beer you're having if you just recorded the number.
The beers are all the same price by the glass, but they vary the size of the glass, regardless of whether that's the right beer for that glass. I could see a beer geek being annoyed by this.
If you do the taster tray, the beers are the same size but the price is unknown. I don't know if that's the long term plan though.
It's cash only right now and no receipts so you have no idea if they charged you correctly.
Also, I'm fascinated by the no tipping plan. I'll be interested to see if it affects service as it reduces incentive to provide excellent service. I couldn't determine if my experience was due to new restaurant or the compensation model.
If I wanted beer and food I'd go here, if I wanted just beer, I'd go to Horse Brass, Bailey's or Apex, having a better tap list for my taste that leans more one-off, barrel aged, etc. This is more Henry's than geeky, as the glasses issue foreshadowed. It's a better take on the concept than Cooper's Hall though, which I feel is even farther down market.
