Great when she's in a good mood but beware...
The owner (I believe she was the owner) was very pleasant until I had a question that she didn't like. Her smile quickly became a scowl and she wasn't very pleasant anymore. She was extremely rude and condescending, and became pretty aggressive towards us in a matter of minutes.
I will be happily returning to the less glamorous, but good quality and far more reasonably priced option a bit south down the street on Roncesvalles, instead of giving my money to a business run by an owner who thinks her customers are a nuisance to scowl at.
Apart from that the prices are hipster high, but I didn't mind for what I perceived to a premium service. Which it wasn't.
