Good coffee and pastries, and simply awesome bistro-style food. I had a chicken panino the last time I visited Bar Mercurio (I've visited a few times), and the panino was one of the best I've ever had - two large pieces of chicken parmigiana on a fresh baked baguette-style bun topped with fresh greens, and sweet potato chips on the side. The espresso based drinks can be somewhat pricey, though they are always made with care. A great place for lunch, or to sit and read with a coffee, especially outside on the beautiful patio!
