Rooftop Gourmet Reverse Champagne Bar

This summer experience from Bompas and Parr leads us in our quest to find out more about the complete history of food to the high rooftops of Belgravia. And I have to say that riding in a tiny lift built some 100 years ago in a building of the same age with two strangers is a pretty terrifying experience. Once to the top of the world we exit out onto a quaint roof terrace. Instantly we are presented with Foe Gras truffles wrapped in gold and we munch them hungrily, only to have our faces turn a meek a sour expression as we quickly look round for somewhere to empty our mouths, there is none, we swallow and regret for the rest of the day as our stomachs try to express the profanity. The staff dressed in white attire with gloves, lead us to a bar where we are served a reverse Champagne, with cognac and some light mixer with grapes where the fizz has been added directly to the grapes. Standing perched above London we fiddle to eat grape, drink for miniature wine glasses, waving an inedible truffle around our heads and thankfully have our undesirables taken from us before being led back downstairs.
Overall a mixed review, the Champagne was pretty interesting but the truffles knocked us off our feet, at least the view was quite breathtaking and the bar man in the top hat was entertaining - 6/10
