FINALLY.
I tried coming here one time before and the line was ridiculously long to get in. Now I have a good understanding of why so many people want to come here! It's POPPIN'!!! I wish they had a place like this in San Francisco where there are dueling pianos and drunken college folks who just sing along whether or not they know the lyrics.
Cover was $6 I think but well worth it since the drinks are fairly inexpensive (from a city girl standard)...$6-7 roughly. You can request songs to the pianists but they'll really only get to your request if you throw in a few dollars for tip. One lady threw in $20 and her song was automatically played. She even got to sit up there with them.
I would definitely come back to the Big Bang when I'm in town next. Bring a few friends, get a table in front (if possible) and enjoy the entertainment.
