Zunzum Gastrobar

Tuna tartlet at the pass

A tuna tartlet leaves the pass before the room has fully gathered its evening noise. Chef Marlene Vieira leads Zunzum Gastrobar in Lisbon and owns it, drawing on Northern Portuguese roots, a long stretch in New York kitchens and work across several Portuguese cities. Her stated approach is to revisit Portuguese bases with contemporary international technique, keeping local ingredients and seasonality at the centre and folding in unconventional elements only when they are not gimmicks.

The room is not organized around a single biographical claim. Zunzum belongs to a restaurant family shaped around modern Portuguese cooking, with this address kept looser and louder than its adjacent formal sibling, the Michelin-starred Marlene. What Zunzum wants is uncomplicated, fun food, where small plates, seafood, pork, rice, bread, dessert, wine, and cocktails all move without turning the place into ceremony. The work asks for a cook who understands the pass as much as the plate. A tartlet can open the meal; octopus can carry the center; cod curry can pull the local pantry toward another set of spices without losing its footing.

Portuguese bases, wider technique

The method at Zunzum starts with familiar materials and refuses to leave them untouched. Swordfish ceviche takes passion fruit for acidity. Arroz de bivalves gathers clams, razor clams, and mussels into a rice dish that reads as coastal rather than nostalgic. Black pork presa meets Madeira-style fried corn, and the bread service brings airy brioche with smoky chouriço pâté before the larger plates begin to arrive. These are not decorative turns. They are decisions about fat, acid, smoke, heat, and texture.

The format gives the kitchen several tempos: à la carte, small plates, and a tasting menu. That range suits a gastrobar, where one table may settle into a sequence of seafood and wine while another stays with cocktails and a few plates. The signatures hold the room together: tuna tartlet, octopus romesco, cod curry. Each depends on proportion. Too much sweetness in the fruit, too much smoke in the pâté, too much sauce against the octopus, and the gesture becomes louder than the ingredient. Zunzum’s Bib Gourmand recognizes quality at good value, but the more useful reading is technical: the kitchen has to make the work repeatable without sanding off its edges.

The room under the trees

The room carries glass, low light, and the energy of Parque das Nações near the water, but the bench remains close to the noise. Zunzum means buzz, and the name fits the service: music in the air, a bar program within reach, tables moving between seafood, pork, rice, and dessert. The veranda terrace sits in a park under trees, softening the modern building without quieting it completely.

Inside, the counter and pass do not feel sealed away from the dining room. Cocktails begin some meals before the first plate lands; Portuguese wines take over when rice, octopus, or pork need a steadier partner. The room is sophisticated without becoming stiff, relaxed without becoming careless. That is the useful tension at Zunzum Gastrobar, and it holds one tuna tartlet at a time.
