What a classic barber shop. The Green Hills Barber Shop is hands down the best in Nashville. Located in the heart of Green Hills, they sport veteran barbers, hot towel shaves, oak hardwood walls and all the ammenities you could ask for...They've turned into a case study of what happens when "web up marketing" is done right. 7 customers a day when we started, almost 20 a day 7 months later.
