San Francisco is highly praised by food lovers. It is famous for some the most delicious foods in the USA. Street Food Festival is not to be missed, for it offers the largest food variety, featuring nearly a hundred vendors who offer everything from Nepalese dumplings or momos to American grilled cheeses. The festival is held in mid-August (3rd weekend of August, to be more precise) and draws around 50,000 attendees every year. The admission to the festival is free, so you just need some cash for food.
