Was in London last weekend - but unfortunately I did not get to spend time in any decent whiskybar.
I went to Boisdale, Victoria, but the place were fully booked and the bar overcrowed to say the least. Word of advice: If you expect to dine there, it would probably be a good idea to book in advance. It did look very inviting though.
After this disapointment, I went to The Atheneum on Picadilly…. Only to find that the whiskybar were closed due to refurbishment. I then tried to locate the library bar / lanesborough hotel, but witout any luck. By then it was getting quite late and I was tired after a long day, so back to the hotel, where I relaxed in the bathtub with a Balvenie Founders Reserve for a while…
