I've been here 3 times now and the first one I was with friends on a busy Friday night. That night made a great first impression. The second two visits I was alone (I'm a single almost middle age woman) and I went when it was clearly off hours and quiet.
Long story short, if you're not in the sausage club clique of regulars forget getting prompt service from the bartender. Also, the sausage club members will do their best to ignore your existence.
I go for the amazing cheap tacos and leave.
