DP said this was the best shave he's ever had and very very relaxing.
It's the one with hot towels and a cut-throat razor followed by lovely shaving oils. You can usually get some sort of massage or facial added on if you like.
I'm in London and DP had his at Genco in Chiswick www.genco-uk.com/the-traditional-barbers-shave/?Itemid=3 where they even provide a G&T to sip while you are having the shave!!
