Studio Nian

”Studio Nian is not a restaurant. We are a pure experience. That freedom lets us create exactly what we wish. We make the experience something truly special.”

Philosophy

GastroVin unites craft and precision in private dining and wine experiences in Stockholm, with quality, balance and storytelling at the centre.

We create evenings where time slows down, where the depth of the wine and the people around the table become something lasting. From Studio Nian in Östermalm we open the door to the most considered dinners of the year.

Catering

Nothing is too small.
Nothing is too grand.

Catering in Stockholm for corporate events, private celebrations, weddings or dinners in the smallest format. Every commission is curated, never standardised. We create complete gastronomic experiences for up to 200 guests: marquees, tableware, glassware, table setting, food, beverages and music.

Transport is part of the craft: by boat in the archipelago, by car, coach or private jet.

The Cellar

The wine is half the story.

GastroVin trades in entire wine cellars and single bottles at auction, with France at the centre. In the cellar rest vintages from the 1920s to the present day, chosen for their stories rather than their labels.

The evenings are built from the cellar: the wine pairings, wine dinners such as Drinking History and the wine tastings where old vintages meet the new kitchen.

Not a restaurant. A pure experience

The studio on Sibyllegatan is the home of our own dinners, tastings and evenings for smaller parties. Here we create exactly what we wish, free from the frames of a restaurant.

The menu follows the season and the company of the evening, and the wines are chosen with the same care as the produce.
