Big city; big buildings; great restaurants; busy traffic; plains and helicopters flying over your head all the time; ambulances and police cars with sirens turned on now and then; people selling stuff to drivers on each red light; those very same lights on the opposite side of the crossing you're standing from (back in Portugal, you stop next to the lights; here, they are placed across the street! not sure if I'm making myself clear on this...)
And people here are very, very friendly :-)
