How’s that mustache coming in? We’re almost a week into Movember, the annual men’s health campaign that encourages growing mustaches to raise awareness and funds for health issues affecting the less-likely-to-go-to-the-doctor set, so there should be some bristly action happening. Give it some encouragement with a frothy treat at Royalton Hotel’s Forty Four bar(44 W. 44th St.) with the Mustache for Mo cocktail. It’s built like an Old Fashioned, then topped with a shot of Espresso Creamed Meringue, which gives you that “Got Milk?” ‘stache after taking a sip. You’ll be in good company, too: The bartenders at Forty Four are all taking part in Movember by growing their own mustaches, and $1 will be donated to the Movember Foundation for each cocktail sold.
