My husband is obsessed with finding and eating fresh seafood - any kind. We've had authentic bouillabaisse in the south of France and sushi in Tokyo at the Tsukiji market (at 4:30am, en route to watch the auctions).
Now we're going to Basque country Mar 30-Apr 5, and he's obsessed with the possibility of the seafood! I've got four guidebooks, and scoured threads here, but am not finding what we're looking for so far...
His ideal situation: a) watch the Basque fishermen return to the port, b) stalk a chef or two who buy the catch off the docks back to their restaurants, c) bide time till lunch when he can enjoy whatever the catch-of-the-day is, simply prepared grilled or roasted with some lemon or wine and herbs. Viola! Happiness :)
There are many seafood restaurants in the coastal towns around San Sebastian, but what is missing (or difficult to discern) in guides we've seen so far is the "hole in the wall" local places that are not known to many tourists, may have no atmosphere, and don't serve the ubiquitous pinxtos - but serve the absolute freshest seafood, prepared very simply in the local style. (This being 'pre-season, the tourist places will likely still be closed for winter.)
We're staying in St. Jean de Luz, about 30 min. from San Sebastian, and will have a car. If anyone has tips on watching the catch come into port, or for these kind of restaurants, I'm grateful for your help!
