Save money at the mini-markets! by wilocrek
Much like many of the old world cities in Europe, the streets of San Francisco are full of corner mini markets that are built right into the neighborhood. The offer inexpensive drinks and many of them have deli's that will make you a fresh sandwich for about $5.99 So if your exploring S.F. on foot keep an eye out for this mini markets and treat yourself to a inexpensive snack or lunch!
