At Marlowe, you can first enjoy their Roasted Bone Marrow dish ($14), finished with capers, salsa verde, and fried garlic. Then, if you ask nicely (even though it's totally not on the menu), a bartender will let you place the hollow bone up to your mouth and will use it as a luge for a shot of Averna Amaro, an Italian liqueur with a caramel flavor and bitter finish, to rinse all of the remaining delicious oils and fat down your palate.
The luge shot will run you an additional $9; order it in the dining room or at the bar and watch patrons around you squirm with envy.
