One of my favorite places in Siena is a café called Quattro Cantoni. Its high arched ceiling and plaster work is stunning, the cappuccino is definitely worth writing home about, and the clientele is an interesting mix of locals and tourists.
One pomodoro, and one with grilled aubergine and fresh mozzarella!
After that, I found it hard to leave. There have been a handful of places in my life that have had a vibe that I can't explain, other than to say that I felt like I belonged there. Some kind of past life thing? I don't know. Like I said, it's hard to explain.
