There is literally no limit of what you can think of people sell in the streets on Ecuador.
If you want, for example, you can live of food from the streets all day long. Some Examples: – Ice cream – Grilled meat – Goodies – Vegetables – Fruits – Magazines/Newspapers – Electronics – CDs/DVDs
A little spanish will help you to figure out prices and to prevent you from getting ripped of. Always check for the right quality, especially with electronics or food. Sometimes they will ask you directly, even if you do not want anything. Stay polite and say a clear “no”.
But nevertheless, I made very good experiences with street food and other things, while following these rules.
