Why go
La Oficina STZ is worth booking for a casual Santurtzi meal built around Cantabrian seafood, pintxos, tortilla, and market-led grill cooking. It suits small groups and returning diners who want the local bar-restaurant version of Basque sourcing rather than a formal tasting-menu experience.
About La Oficina STZ
La Oficina STZ is a casual Santurtzi venue for seasonal Basque seafood and pintxos. The essentials are direct: chef Jon Belloso Morales leads a kitchen associated with Cantabrian seasonal fish a la brasa, patatas Torrikas con salsa Punch, tortilla de patata, and pintxos de temporada. It is best considered when the next meal should be Basque, seafood-led, and informal.
The useful way to think about it is this: go for the seasonal seafood and pintxos. The price is about $40 per person, and the dress code is casual. That makes the value case clearest for diners who want grilled Cantabrian fish, tortilla, seasonal pintxos, and a relaxed Santurtzi stop.
Order around the Cantabrian fish and seasonal pintxos
The strongest move is to start with the house signatures. Pintxos de temporada and tortilla de patata are the low-risk way in; patatas Torrikas with salsa Punch are the more specific house order if the table wants something tied closely to La Oficina STZ. For the main decision, steer toward Cantabrian seasonal fish a la brasa when available.
That also means the right mindset is flexible. Seasonal cooking depends on what is available, so it is better to ask what is strongest that day than to arrive with one exact dish in mind. Chef Jon Belloso Morales’s role matters less as celebrity biography and more as a practical signal: the cooking is tied to seasonal Basque seafood and pintxos in Santurtzi.
Keep the meal centered on the food: seasonal seafood, pintxos, and a clear price point.
Plan around the published hours and casual dress code
Casual dress is the right call.
For planning, use the listed schedule and the $40 per person price as the main practical anchors. La Oficina STZ is closed Monday; open Tuesday and Wednesday 9:00–22:00, Thursday 9:00–23:30, Friday and Saturday 9:00–00:30, and Sunday 9:00–18:00. A visit makes the most sense when the group wants seasonal Basque seafood and pintxos in Santurtzi.
Recognition is modest but useful for context: La Oficina STZ has a Macarfi 7.4 Food Rating for 2026. That supports the idea of a Santurtzi seafood-and-pintxos address valued for its food.
How to fit it into a Santurtzi food day
