I will arrive in Mexico City @ 5:30 a.m. I imagine it will take me a little while to go through customs and take a cab into the city. I figure I will be in the city right when restaurants are opening for breakfast. Here is what I need - a great restaurant in a central area where I can walk/sightsee after eating. I have never been to Mexico City and probably won't be back for a while. I am open to all types of restaurants (hotels, holes in the wall, etc.).
