What smells most in a bakery?

Although it is actually surprisingly difficult to convey the sense of smell over the internet, I think I can safely answer, in a way that you will almost definitely understand, what bread actually smells like: Bread, of course, smells like bread, and although I fully understand that the medium of the internet may not be enough to stir those parts of the mind with which the comprehension of the chemicals in a loaf of bread, or in anything else that 'smells' for that matter, is dealt, I am afraid that this is the best answer that you, or anybody else, could possibly receive without actually going out and smelling the bread for themselves.
