Rooted in the basement of the Jurys Boston Hotel Cuffs bills itself as an Irish bar. But this is Dublin by way of Beverly Hills with a duty-free layover in Tokyo. There’s a bloom of youth and money on the patrons who even if they’re holding pints of Guinness spend as much time on their cell phones as in their cups and dress in tailored wardrobes as well pressed as their complexions. Once the crush of beautiful people reaches critical mass it spills upstairs into the low leather seats of the Stanhope Grille.
