Went to a concert here tonight at the shelter and was completely disappointed by the bartending. It would take 20 min to get a drink because two were on staff and when asking for a certain liquor she said no we don't have this, but it was sitting right there. They seemed to have no clue what was going on. I'm not sure if this is how its usually staffed but some help and bartending classes would help.
