A different world maybe, but a very run down feeling world.
If you have some time to kill, its definitely something to wander through but it is very run down. The variety is interesting and it does feel like a different world. The street performers, while touristy, were entertaining. It is crowded, fairly safe and easy to navigate. It seems more authentic than NYC in that you don't see junk knock offs, but more like a functioning market, vegetable stand and butcher for the local residents mixed in with cell phone stores, 5 and dime type and appliance stores. There are plenty of restaurants. You can pretty much do a 15 minute walk through and see it or stay and explore longer if you like.
