"Barrelproof Boutique is a specialty store for spirits and cocktails. Here you’ll find the best Mezcals, Gins, Vodka’s and other spirits from all over the world. You might meet Arno - a worldwide known bar and cocktail specialist. Ask him for the number of the Dr., an award winning speakeasy bar located somewhere in Rotterdam. The boutique is a reminiscence of America in the 1930’s; warm and cozy, jazzy tunes, the smell of spices, and very friendly staff to help you pick your new favourite spirit." - Mangrove
