"The Pre-Lunch Vermouth Tradition On a cold Sunday late morning, when the first pangs of hunger are starting to hit, nothing tastes better than a glass of vermouth. Straight up vermouth is an aperitif of choice, especially on weekends, in San Sebastián . Bar Etxebarria serves up their own special blend, only on the weekends, only before lunch. This is authenticity at its most delicious; the perfect way to start lunch."
