Housed in a cheery yellow building on SoMa's restaurant-lined Fourth Street, unassuming Fringale is just the sort of intimate bistro this neighborhood needs: petite, hospitable, utterly charming, and delicious every time. The menu satisfies with authentic Basque cuisine and a decidedly French accent. A perfect beginning is found in the spicy Monterey calamari grilled a la plancha with piment d'Espelette and briny olives. Other bistro favorites might include crispy duck confit paired with French lentils, salty bacon, and drizzled with a tangy red wine sauce; sautéed prawns in Pastis; and heart-warming daily specials like boeuf Bourguignon. For dessert, try Mme. Angèle's gâteau Basque, a buttery almond torte filled with custard cream.
