Here's what I could gather.
LMDW Fine Spirits is an ofshot of La Maison du Whisky (hence LMDW).
It's mostly a shop with 3 floors offering fine whisky, rum, cognac, calvados, armagnac, tequila, mezcal, cachaça, vodka, gin, fruit eau-de-vies, grappa, vermouth, cocktail bitters...as well as sake, a selection of teas, coffees, spices and cocktail and tasting accessories.
The first floor is set as a professional bar surrounded by everything the amateur mixologist might want to play bartender at home.
It will also host classes for amateurs and professionals alike and showcases for specific brands like St Germain (made from hand-picked elderflower blossoms) or hosting parties as they did December 2 for GQ Magazine (French edition).
Forest Collins called the 'bar' part, 'bar ephemere' (ephemeral bar) yet it seems to be built to last at least it will not turn into pixie dust come January 1st.
In a nutshell, not a place to spend the evening, rather somwhere to discover new flavors, ideas, concoctions and shop a little before heading out.
I will hopefully manage to fetch a couple of Cocktail Recipes from them soon.
Opening Hours Are: 11 AM to 8 PM (Tuesday and Wednesday), 11 AM to ( PM (Thursday and Friday),
10 AM to 8 PM (Saturday)
