Was Lanson in T2 last week when I was in, this week was Taittinger, although both were self serve, the bottle of Taittinger was empty and I had to ask a lounge host for a replacement bottle, took a few mins. No bathrooms in the business side either, all closed for maintenance, so first toilets available. I hope they keep up the Lanson and Taittinger combo...it helps soothe the soul given the lack of any windows or natural light in a so called flagship lounge!
