Marisquería Esthvan focuses on traditional Galician seafood preparations using classic cooking methods and seasonal ingredients. The menu centres on fresh fish and shellfish prepared without culinary innovation, letting the natural flavours shine through honest, authentic techniques. Expect daily seafood availability alongside permanent Galician classics served à la carte.

The restaurant is at Palència, 45, on the corner of Honduras, in the Navas neighbourhood of Barcelona's Sant Andreu district. The nearest metro stations are Bac de Roda (L2), a 10-minute walk, and Sant Martí (L2), an 11-minute walk. La Sagrera rail hub is roughly 12 minutes on foot.

Reservations are recommended and are taken by phone on +34 933 514 701. The dining room is small, so weekend walk-ins are often turned away; midweek lunch is the easiest time to be seated without booking.

Mains sit in the mid €20s, for example hake with sherry vinegar at €24, suquet de rape at €25.95, entrecot a la gallega at €23, so a three-course dinner with wine typically lands around €50–60 per person. Shellfish-counter items (oysters, spider crab, clams) are priced by weight and can push the bill higher.

The restaurant serves lunch Tuesday through Sunday (11:30–17:00), but extends dinner service only on Friday and Saturday evenings (20:00–23:00). This schedule reflects the neighbourhood dining culture in Navas and Sant Andreu, where many family-run restaurants focus primarily on lunch trade through the week.

The restaurant presents a welcoming neighbourhood atmosphere with functional decor and professional service. The setting is cozy, casual, and rustic, creating an unpretentious environment perfect for enjoying traditional seafood.
