Good quality bar, pastry shop, and ice cream parlor, prices a bit high.
I've read many reviews that insist on the rudeness of a cashier who behaves rudely with customers. It's never happened to me; if it were to happen, I'd respond in kind and report it to the owner immediately, even for a discussion. Post-hoc reviews don't help matters. This historic bar isn't located "at the end of the world," but in the southern part of the city, well-served by public transportation and full of supermarkets, shops, and services.
It's certainly not a vibrant area... so much the better.
