"American sommelier Brian Patterson, his wife, Jenn, and their massive Leonberger-Retriever mix, Bear (the Beartender!) are the consummate hosts at Lisbon's newest, most interesting, and surely smallest wine bar. Located on pretty Praça das Flores in Principe Real, Patterson curates his all-natural wine list with a laser focus on small producers from around Portugal. He sources his finds on reconnaissance drinking missions around the country, including some of Portugal's more underdog wine regions. His updated-daily chalkboard menu includes a half dozen or so offerings by the glass (€3.50-7) along with two batch cocktails, as well as intriguing bar snacks to accompany (his hummus is destination-worthy in and of itself). The bar doubles as a bottle shop; rightfully so, there is only room at the bar for about 11 provided everyone is sucking in their wine guts. File under: Wine Revelation."
