Hard to find on purpose, this Rittenhouse cocktail bar sits behind an unmarked door on Ranstead Street and earns its reputation quietly. The drink program is the whole reason to come: house infusions like lemongrass gin, earl grey bourbon, and sesame-infused shochu show up in complex, multi-ingredient builds that are inventive without being showy. If you can't decide, the Bartender's Choice ($20) is worth it... answer a few questions and they'll make something for you.
