Founder Alex Dehayen will launch two-storey Chiringuito this month, along with Peruvian head chef Marco Padilla.
The all-day menu, which is designed for sharing, will mix South American flavours with traditional Spanish tapas dishes, including padron peppers; patatas bravas; manchego cheese with honey and figs; and gambas al ajillo.
Peruvian and Mexican-inspired dishes will include seabass ceviche with leche del tigre; swordfish tacos with elderberry jam; roast pork belly in pisco and beer sauce with Peruvian chillies.
The bar will specialise in gin and tonics, and will offer a wide variety of Spanish gins alongside cocktail and wine lists.
Décor will feature floor-to-ceiling windows and Spanish influences including blue mosaic tiles and a hand-painted mural.
“I wanted to bring something new and different to the place where I lived, to capture something that I loved from Spain and Latin American countries, which seemed to be missing in London,” says founder Dehayen.
“I love the vibe of the chiringuitos, as they are places where everyone is always welcome, where you can sit all day, won’t be rushed through service or hurried to leave – in fact you are encouraged to stay”.
Chiringuito will be the second South American restaurant to launch in Bethnal Green in the past few months, following the opening of Arepa & Co on Paradise Row in April.
