i would add that if you are prepared to put your camera away and are prepared to buy some stuff, in particular, there is always lots of places that will package up some of the less perfect cuts of varying grades of tuna for purchase - prices range from 500 - 2500, some i had were around 2200 this time and was some very very nice fatty pieces of odd shapes and sizes - and look for some other goodies to buy, you should be fine in the inner market afterwards - even at 6:30. that said, you even pull out your camera once or someone, in particular, security sees a flash, you will be frog marched out.

so if it were me and i did not want to wait around and was fine having my memories and reference to the thousands of others photos out there, i would buy some great tuna and a few other of the deep fried snacks and walk around. just walk around like you have a purpose and know where you are going and watch out for the people working.
