Prime of prime locations, the 'mirrors' cafe sits on Piazza Unità d'Italia, Trieste's gem of a main square. Of course the price you pay reflects the spot, but this is a place with a lot of history, in a famous coffee town. That combined with the location means that finding a outside on a sunny day (or inside if the weather is being uncooperative) can be a monumental task, especially when there's a 'unity square' event going on.
