"The tortilla de patatas at Bar Néstor (Calle de la Pescadería, 11) in San Sebastián is the stuff of legend. Potato, free-range eggs, olive oil, onion and green peppers work together to create this miracle. Only two omelettes are made a day; one is served at 1pm and the other one at 8pm. In the summer there can be lines of around 30 people, so run for it!"

"It is still warm, dribbling egg yolk out via its sides on to the plate. In my experience very few dishes in life live up to the hype. This does. Maybe its the terroir, or the anticipation, but this is one of the very best things I have ever eaten, a shock even to me given that this is essentially made up of just eggs, potato, and onion. It is luscious and decadent, comforting and humble."

"Bar Nestor is famous for their delicious Tortilla de Patata. Actually, some people rate it as the best there is to find. All over Spain."

Kang Leong

"This luscious egg sauce giving this sensation of warm, gelled potatoes inside the omelette, like that of a moist mud cake. The key are caramalised onions – added to olive oil, eggs and potatoes – which makes this tortilla so sought after."

Marti Kilpatrick

"It is indisputable that one of the city's most delicious is that of Bar Nestor. It's a masterpiece that is very underdone in the middle and gloriously orange."

Brittany Jeffs

"Bar Nestor’s version was worth all the effort and the hype and it still remains the best tortilla I’ve ever had. The potatoes had a caramelised texture and taste that you don’t often find in a standard tortilla, the dish had this crispy top that made it taste so much better than your average tortilla."

Jordi Luque Sanz

"The omelet is golden and runny and extremely delicious – in short, it ticks all the boxes."

Sam Stewart

"A must, must visit and the best tapas in San Sebastian."

Sorrel Downer

"And at 1pm and 8pm they bring out one tortilla – only one. You only get a piece if you’ve come early and ordered it in advance. It’s pure magic.”

Sam Stewart

"They are well known for their traditional tortilla (eggs and potatoes)."
