Huge line to get into the restaurant, and huge line to order the food once your inside. It probably took us 40minutes to get inside and another 40minutes to get the food (It was a Saturday night though - maybe it gets better during the week). They don't do reservations for parties of less than 10.
The sausages themselves are good - they have great vegan options that are tasty. It is very big and filling. Their salad wasn't very good but I guess that's not what people come here for. All my friends got the duck fat fries with their sausages and they seemed like a hit.
Also they have a huge beer and cider menu, and do a fun little taster of six different ciders or beers to share (or not ;).
Was a little pricey but a fun experience. I can see why its popular.
