That's always a tough question to answer. On the one hand, it's an extremely safe area. It's very busy; there are a million people around -most just trying to get back and forth to work. You almost certainly are not going to get mugged or stabbed or anything.
But on the other hand, if you are a squeaky-clean white person from suburbia, you are going to stick out a bit. Nobody will care, but if you aren't used to spending time in the city, *you* might feel a bit uncomfortable, especially if you are there at night, or first thing in the morning when less people are around.
