The basement at Hix Soho is consistently busy in the evening. And we understand why: this is a first-rate bar in nearly every respect. The historical drinks are both interesting and good, especially those in the Cocktail Explorer’s Club list; rum drinkers should make a beeline for the Royal Bermuda Yacht Club: Mount Gay Barbados rum with orange curacao, Mark’s own falernum and lime juice. The selection of scotch would take several months to drink through. The bar ‘snax’ are terrific, and you can also order from the carte if you want something substantial. And the place looks great, with its big smoked mirrors. Our only complaint is the lighting, subdued in some places and too bright in others. Also worth remembering: there are more spaces for larger groups than for just a couple. Not a complaint, just an observation. The quibbles don’t detract greatly from the classiness of Mark’s.
