Background

About The Diner

The Story

The Diner comes from the people behind Watts Cantina and bills itself as a trusted neighbourhood diner. The team put the room on Costanilla de San Andrés through a heavy build-out, and has since added its own merch and its first night-time pub evenings.

The Cuisine

Creative American diner food, built around breakfast and sandwiches: a breakfast burrito with avocado and spicy pineapple sauce, and an Italian hero with spicy spianata, salame, pesto rosso, pickled aubergine and mozzarella.

Getting There

Costanilla de San Andrés 20, 28005, in La Latina, in the old streets around Plaza de la Paja.

Nearby

La Latina is where the city goes to graze, a slope of narrow streets built for moving between bars rather than sitting still. The eating is social and unhurried, and El Rastro brings the crowds on market days. Mercado de San Miguel and Plaza Mayor are the polished edge; the good stuff is further in.
