Granada's seafood institution on Calle Navas
Calle Navas is Granada's main tapas corridor, a narrow street running south from Plaza del Carmen that fills with people from lunchtime until well past midnight. Bar Los Diamantes, at number 28, is the one with the open kitchen visible from the door and the smell of hot olive oil reaching the pavement. It has been serving fresh seafood tapas to the people of Centro for years.
In Granada, every drink order comes with a free tapa. This is one of the few cities in Spain where the tradition holds, and Los Diamantes uses it to show off their kitchen: fried calamares, a small paper cone of espetos, or a plate of boquerones arrive with your glass without any extra charge.
What comes out of the kitchen
The cooking is Andalusian: high-heat, fast, with good oil. Espetos (fried small fish) come in paper cones, hot and salty. The calamares rebozados are properly battered, not the frozen variety. Boquerones arrive either in vinegar (en vinagre, sharp and white) or freshly fried. The rabo de toro occasionally appears as a free tapa and is the surprise worth waiting for.
Nothing about the menu is complicated. The kitchen does a small number of things well and repeats them hundreds of times a day. Locals eat at the standing-room bar; tourists sometimes look confused that the menu is limited. That is the point.
The bar itself
The interior is functional: a long bar, a few wall tiles, the kitchen open behind the counter. The staff work quickly and do not linger over explanations. Point at what someone else is eating if you need to. The bar fills from noon on weekdays and by 13:30 on weekends there are people spilling onto the street.
Prices are as low as tapas bars get in Granada. A beer or glass of wine costs around €2–3, and the free tapa comes with it. If you want more, order another drink.
Finding it and when to go
Calle Navas is easy to find: walk south from Plaza del Carmen, past the town hall. Los Diamantes is about 200 metres down on the right. Open from noon daily. The quietest window on weekdays is 12:00–13:30 before the lunch rush. On weekend evenings after 21:00, expect to wait for a spot at the bar.
