Sadly Gareth is correct.
Although most soulies are happy paying £250 for a tune they will object to paying £4 a pint
Soulies will be over critical on the DJ, music policy, lights, dance floor, food, range of beer etc........ruining a lovely idea!
If you want to make money in a music bar in London your target audience would have to be much younger - around 20 to 40 years.
Thats the age group spending the cash on a regular basis.
