The Marylebone does something that no one else in London does - at least as far as we're aware. Rather than just making a few infusions and using them in cocktails, it makes dozens of the things - and serves them on their own as well as mixing them into drinks.
A selection from what they make includes cherry rum, mango vodka and clementine gin. You can order 5 for £15 or 8 for £20, and they're served on tasting boards. The cocktail list is brief but inventive and, at £7.95 across the board, extremely well priced for a place in W1.
Food is minimal: sharing platters with a Middle Eastern bias. But with advance notice they will arrange for other food to be brought in from nearby restaurants.
