I want to visit Etxebarri when the dining room is full and has energy. Many pictures I've seen on the web show a dining room with only one or two tables occupied. My general experience is that this makes for a rather depressing meal (no matter how good the food is).
I have a reso for dinner on Saturday at 10pm. I know the Spanish eat dinner very late compared to many other countries. But I also know the Spanish eat their big meal of day in the afternoon. Will the place be happening or more of a snooze?
