I get the smoke, obviously, but from whence the Butter and Lemon? Sounds interesting. Also sounds like the sort of thing I might prefer neat. If you like this, you might try the Bernet Frankenstein, a mixture of Islay Scotch, Punt e Mes, and Fernet Branca, served neat.
One question: is the garnish a lemon wedge, slice, or what. It's a bit hard to tell in the picture. It also looks like the coupe is rimmed with something, but it might just be the light hitting it oddly.
