King Cole Bar & Salon (click here for address and deets)
Revamped by the dude behind The Lion and Bill's Food & Drink, KCB&S is the spot where the first-ever Bloody Mary was served (though back in the '30s, it was known as the 'Red Snapper'). You can still order the $25 classic, sip in front of their famed King Cole mural, and ask the bartenders about the riddle that's hidden in the painting.
Essential Cocktail: It remains the Bloody Mary, served here heavy on the Worcestershire and light on the horseradish.
Wallflower (click here for address and deets)
This shoebox of a spot comes from the team behind Mother's Ruin on Spring St, and features former Daniel barkeep Xavier Herit behind a really tiny bar doing all kinds of awesome, including bottle-carbonating cocktails and chipotle-infusing spirits.
Essential Cocktail: The Betty Draper, a ready-for-Winter, gin-and-calvados special with Sherry, celery juice, apple bitters, and awkward feelings towards that neighbor boy Glen.
