One of the coolest spots in the city is the fish market. Fresh-caught seafood and all kinds of fish are brought in throughout the day. The fishing boat captain sells the catch at auction, it goes to regular vendors, and then finally to the end consumer.

Sometimes the fish you buy doesn't go home with you—instead, you cross the street where specially trained folks will cook it for you, and you can eat it right away.

Taking photos at the market is tricky though. The local security guards see a camera and immediately swoop in: "Hey, what are you photographing? No way, stop right now!" And then they offer to sell you permission for a "photo session." They'll even print you a receipt :)

I tried to get away without permission, but ended up having to spend some cash. The "permission" comes with a guide included—one of those same security guards. He wasn't much help, except for one time when he shooed away a beggar. To be fair, that was literally the only beggar I saw all day.

The atmosphere is incredible. The real action happens early in the morning, but it's interesting even during the day.
