If you really like to feel the latino vibes. U must take a tour into the heart of Mission District. Not only that neighbourhood is totaly different then the North side of San francisco, it does really feel like you are in South-America. So different then in Belgium where you have also neighbourhoods with immigrants but they still look Western with a exotic touch. There the architecture, the noise, the people, the stores really look like you're on the South of the Americas. But most important when you take the bus over there is to have a walk (guided is possible) along the great murals that speak of the indigeneous people that are oppresed by the European discovery missions. I will let the pictures speak for itself.
I didn't have time or oocasion to taste some of the latino food alas.
