Tip: Brasa lights at 12:30 and 20:00.
Why locals love it: Same family as Ganbara but a tighter, quieter counter on Plaza de la Constitucion that even guidebook regulars skip.

Casa 887 ★ 4.3
Why locals love it: Gros stone-basement room of Brazilian chef Antonio Belotti with a 65-euro tasting that locals book midweek and tourists rarely find.

Sirimiri Gastroleku ★ 4.2
Why locals love it: Calle Mayor counter close to Bretxa that pulls Bretxa-market shoppers more than tourists.

Why locals love it: Tucked above the Old Town with a Bay-of-Biscay terrace, the city's quietest harbour-side cider stop.
Tip: Closed Mondays and Tuesdays. The terrace fills first; arrive before 19:00.
Bideluze ★ 4.0
Why locals love it: Plaza Gipuzkoa breakfast counter with retro tile floors that locals love and tourists walk past.
