This is really a 4.5. I can't give a 5 because of the coffee - that may be cruel, but a pastry place should have very good coffee, too.
That said, the pastries are top-notch. I'm not much of a sweets person, but I've never had something I didn't really like. Even things like almond horns - I would rarely consider getting this, but at Mirabelle they look so good, I can't resist.
The biscotti are fantastic.
