Cool, bi-level bar serving izakaya fare & traditional American bites, plus whimsical cocktails. Like its playful name suggests, Katana Kitten—another World’s 50 Best Bars list-maker—is equal parts sleek Japanese precision and whimsical fun, thanks in no small part to its ever-grinning proprietor Masahiro Urushido who brings his sharply-honed mixology sensibility to offbeat highballs, quirky signature cocktails like the horchata and ancho-infused Leche de Gato, and, yes, a full selection of boilermakers for a high-low experience that will definitely have you ready for a second round.
