Inexpensive things to do in San Francisco

well, I have been to san fran 3 times, and I like to go to the bridge and walk it, that is cool and you don’t have to pay anything. Also, there is a giardelli shop with amazing shakes. They are only less than 5 dollars. Also, the Teddy Bear shop has really good carmel apples and hot chocolate. To eat there is a Rainforest Cafe’ and I really like their food, also, they have activities, a shop, and animals there. It is a great environment to be in. There is a Barnes and Nobles there that you can go read and not have to buy the books. Also, my favorite thing is going to Alcatraz Island. There used to be a prison there, you can get an audio tour thing, or just look around, but I like seeing the prison, and what it looked like. I don’t remember it being expensive, but you get a boat ride there, so I am guessing it was about 10 dollars. Have fun!!! Hope you try these things!!!:)
