Charlie’s isn’t named after it’s chef, it’s named after Lord Charles Forte, one of the founding members of Brown’s Hotel in Mayfair. All very Downton Abbey, right? Yes, but the food isn’t. The new upmarket restaurant inside Brown’s has a menu full of modern takes on British classics, and the space itself has big booths, lots of wooden panelling, and enough botanical wallpaper to make a gardener blush.
