Why Ettu is worth a table
Ettu is the restaurant of Hotel Olom, on the Plaza de la Catedral, directly opposite Cádiz Cathedral in the Santa María quarter. It is listed in the Guía Repsol 2026 as a recommended restaurant, and it is the room to pick when you want a considered dinner rather than a plate of fried fish at the bar. The kitchen sets out to do something most of the old town does not: put Cádiz produce through a Mexican filter.
The kitchen: Cádiz with a travelling outlook
The restaurant describes its cooking as Cádiz cuisine with a travelling soul, built on local, seasonal produce and recipes rewritten in a contemporary language. Guía Repsol frames it as a dialogue between Andalusian heritage and Mexican cooking. Press coverage names Luis Callealta as gastronomic director and Álvaro Vela as the chef running the kitchen day to day, so expect a menu shaped by the fish and vegetables of the bay rather than imported theatre.
Guía Repsol's recommended dishes are tuna tartare with carabinero, noodles with mackerel and a pistachio coulant. Some dishes are finished at the table, such as the tuna tartare with bone marrow. The menu changes with the season, so treat any dish list as a snapshot and ask what is current when you sit down.
The patio and the room
Ettu sits in one of the last private patios in the city centre, which is why it feels removed from the square outside. A terrace shaded by an olive tree and a dining room with pieces by Cádiz craftspeople, including clay botijo water jugs and leather cutlery sleeves, give it a calm, domestic scale. The hotel also houses the Aleph Cocktail Club, so a drink before dinner is easy to arrange.
Prices, hours and booking
Guía Repsol lists a price band of €35 to €60 per person; that listing is undated, so confirm against the current menu when you book. The same listing shows Sunday service as lunch from 13:30 to 15:30 and dinner from 20:00 to 23:30; for other days, phone ahead.
Book through the restaurant's website or by phone. Its booking page asks guests to report any allergy, intolerance or dietary restriction in advance, so do it when you reserve, not at the table.
Where it fits in a day
The cathedral and the Santa María streets are on the doorstep, so Ettu works well after an afternoon in the old town. If you are comparing it with the city's other serious rooms, Mare is a smaller, tasting-menu-only alternative; Ettu is the more relaxed choice with an open patio.
