I've heard every range of commentaries on Barley House that is possible. In my opinion Barley House does a better job at reinventing itself throughout the day then anyone. It is most certainly an Irish pub for lunch and happy hour. It is a sports bar for any big sporting event. And it is a packed night club with incredible DJ's, Vegas style lighting and great sound system.
The staff is very professional and go out of their way to make you feel special and wanted. They have more security then any other club on West 6th and my entire party always feels safe and secure. They actually have a great VIP area and an enclosed open air back "grotto" for those that want to have walls around you but still have fresh air. Then there is the side patio complete with Cabanas and outdoor televisions to hang with friends, have fresh air and still catch the game.
One thing I think that is overlooked is the food. They have an awesome selection of items from simple bar food to salmon and crab legs (which are all you can eat on Monday's for like 20$).
Just my opinion but I spend my money there consistently for a reason. Great environment, staff and experience.
