Palmano's is a great place if you're looking for high quality (rich and sweet) espresso. They roast their own beans and have great coffee, latte and cappucinos as well. There is a good selection of snacks and pastries, and a nice outside seating area. (There are also fans)
Inside the bar, the quarters are a little crammed with just a couple places to sit, and at times you want to ask the staff if they should be in school, but they do a great job and are friendly and attentive.
They also have a selection of fine roasted coffees on hand from various origins. Prices are reasonable.
