In the heart of the Old Town, where every alley breathes tradition, lies Vermutería RIO—a legendary gastronomic establishment without which it is impossible to imagine the city of Pamplona. Opened by the Barberena family back in 1963, this authentic bar has evolved over decades into a true symbol of regional cuisine, highly valued throughout Spain.

The pride of the house is the famous frito de huevo (deep-fried egg). This crispy pintxo has become so popular that the counter for portions sold is nearing the incredible mark of two million. Unlike many modern venues, they focus on the impeccable quality of local products and loyalty to Navarre's street food culture, serving snacks as fresh as possible.
In October 2025, the establishment's status was officially confirmed with the prestigious "Best Pintxos Bar" award at the Basque Country and Navarre Championship. Despite critical acclaim and high ratings, Vermutería RIO maintains the simple and lively atmosphere of a classic bar, where conversation at the counter and sincere hospitality remain the central elements.
