Fantastic spot. It's a bit far from the center, but its actually a really nice walk through town if you decide to walk it. The metro station is literally right out front also if the walk is not possible for you.
There were TONS of options and the case was fully stocked at 12 on a Sunday afternoon. We went crazy and got a bit of everything. Recommend the pastel de natas :) see my picture below for some of the treats we got!
