The Maybourne has a few spots to pull up for a cocktail, but for something a little dramatic, plan a night at the Cigar & Whiskey Bar. This reservation-only bar is hidden on the second floor (you'll get escorted up a back staircase) with 1,000+ cigars in stock (for hotel guests only, but cool to look at) and a booklet of whiskies sorted by country. There’s a $100 per person minimum, but that's not difficult to hit, considering the per-ounce price of some premium bottles. Or, just order off the cocktail list—they make an excellent Penicillin.
