Wine tasting at Vinopolis is a fabulous way to spend an afternoon - just make sure you don't have to function responsibly after you leave.
We did the Vintage Wine Tasting tour and got to sample some awesome wines from all over the world. The benefit of wine-tasting at this place, is that you can try wines you may not do otherwise (I'm biased, so I tend to favour Australian wines). This particular day, we tried everything from Argentinian wines to authentic portuguese ports and some great reserve wines.
Set beneath the arches of an old Victorian viaduct, just behind Borough Markets at London Bridge, Vinopolis is a great venue for wine-tasting and corporate venues alike - Factiva held a customer event here a couple of years ago, and the unique nature of the venue makes it an unforgettable experience.
