Jus Do It

By The Editors

Trunks weather is nigh, señor. Time to let the air out of the spare.

Redouble your gym efforts.

And, dare we say it, start a cleanse.

Clap your hands for Gaucho Mark’s — now open on Divisadero at Bush (former King of Falafel location) — purveyors of the first ever Brazilian Jus Cleanse.

Yes, a Brazilian steak juicery offering SF’s first-ever beef juice cleanse, chock full of protein and prepared churrascaria-style.

Think gourmet French dip minus the sandwich, with Gaucho’s exclusive and flavorful au jus (beef roasting-pot juices) and concentrated erva mate.

Each batch delivered hot daily in a vintage Stanley thermos by a bombachas-bedecked bicycle courier.

This is about looking forward. And looking good poolside.

Nota bene: Delivery is limited to the city, but daily pick-up is available on location. Thermos availability is limited, though, so sign up on the double.
