One of the websites suggested a typical Milanese breakfast of coffee and pastry at Marchesi. Sure, I thought, that sounds like a good start to the day. I probably should have taken notice that it's located on Monte Napoleone, the ridiculously expensive designer street. No wonder it looked like a nice clean attractive place on the inside. No wonder the coffee menu started from €5 per drink. Oh well, can't sit down then leave...
The coffees were adequate (as they should be for the price...) and the pastries were ok too.
I'd have to say I don't need that kind of atmosphere (as lovely as it is) and would be much happier in a nice standard bakery like Princi... (http://eatlikeushi.posthaven.com/princi-milan-09-2017).
But if you want somewhere nice to spend your money (as is the way for some in Milan), then you'll be in your comfort zone here.
