There are some perks and downfalls with Plan B. They have good music and DJ's every night, and they also have events once in a while. They have friendly, experienced bartenders. In addition they have some good drink deals.
The downfall is that there is a cover fee every night you go in. I would understand if there was an event going on or something. But if it's a random Friday night, and you only allow 21+ people in who basically all drink/purchase alcohol, I don't see the point of charging between $5-$10 to allow people in. Another downfall I have with Plan B is that the female bathroom stalls don't lock and I had to use my foot while in there. I felt like someone would just come into the stall I was in. Also, the bathrooms were extremely dirty for it being dead on a Friday night at 10 PM.
