There are other "Leather Bottle"s than this one in Cobham. It is 12.5 pounds taxi ride away from the Olde Leather Bottle in Gravesend, which is a pub/restaurant. In England, they use the DA12 3BZ to find places - give that to the taxi driver, and maybe you won't have to call a second taxi to go to the correct Leather Bottle!
Cobham is very small, with nothing much to see except a lovely old church. The last problem I had was that I couldn't figure out how to make the shower turn on. It had an unfamiliar box with a button for on/off and two dials for temperature and pressure, but nothing worked. Ask for help with that when you check in.
The people were very nice, and left us breakfast sandwiches since we had to leave very early in the morning.
