La Taqueria - If you like really good carnitas and appreciate super fresh and delicious Agua Frescas and don't mind (or prefer) burritos minus the beans - this is your place. Since beans are cheaper than meat, the burritos here may be a better value than those loaded with frijoles. The ingredients are fresh and the resulting food is top notch. They have carne asada (beef), carnitas (pork), lengua (beef tongue), cebeza (head), pollo (chicken), and veggie. The Agua Frescas here are really good. There is so much fruit you can eat them with a spoon; phooey on you if you order a Coke. Recommended.
Le Charm French Bistro This restaurant is another proverbial jewel hidden in plain sight on a really yucky street (5th between Folsom and Harrison). Le Charm is notable for having a charming trellised patio, solid French Bistro food, and a continual Prix Fixe $25 dinner menu that has to be one of the great bargains in San Francisco. The menu has exactly what you would expect: French Onion Soup, Seamed Mussels, Duck Confit, Cassoulet, Grilled Steak with Pommes Frites, & etc. Recommended.
