Callooh Callay is a cocktail bar in Shoreditch that runs a front bar and a larger back room behind a mirror door. Its menu draws on Tinder for creative cocktails such as the Green Card and an Old Fashioned with tomato and mushroom notes. Past the mirror door is a hidden back room, and reservations may be required after 9 p.m. Prices are on the high side relative to the quantity and quality of the drinks.
