I agree you should give it a try. The ones I have had were not as close of a shave as I could do myself. But having the hot towels, warm shave cream/soap, and the barber going over your head is like a good massage. I find it very relaxing. I have paid form $15 to $35 for the service, plus a tip. And the $15 shave was just as good as the $35 shave.
Just make sure you are getting a straight razor shave. My normal barber was out once and I let another barber, in the same shop, give me what I thought would be the same service. But the other barber did not use a straight razor, just a cheap cartridge razor. It was not the same experience at all.
I was told that for straight razor shaves they can only shave with the grain.
