At first blush, the Sanderson struck us as a hotel specifically in the Mondrian vein (perhaps while the hotel group was reforming as Morgans and the brand’s expansion was not yet a consideration)? The Sanderson is spacious, white, and Pantone-pastel accented, with a long narrow table reminiscent of the Mondrian’s ADCB and a martini menu with an ever slight customization of £ pricing. On the rare occasion when we want a little sugar in our drink, we love the Mondrian’s sour apple martini, and the Sanderson’s lived up to the stiff, tongue-recoiling tartness.
