We stumbled across this by accident, having visited the free Quechua Museum, (which has access into the same courtyard and is also excellent) and what a find!
It is Alice In Wonderland themed and totally fabulous. I took photos but realistically they are already in the album attached here. Ana explained that she made the large scale rabbit, hat, pots and tea display herself along with her father - based on her childhood love of the Alice story.
We were in the quaint ‘tea bar’ fronting the street, which only has seating for four - a cosy and friendly environment. The larger tea room as seen in the photo is usually open, but was unstaffed today.
Ana was so friendly and speaks great English. We had ‘mixto’ toasted sandwiches, a Dulce de Lethe churro and sampled the recommended Coca tea, having just arrived here. Ana has such a variety of teas, if we have chance to return I would like to try some of her unusual teas. Our tea was made in a pot allowing two generous cups each. I asked if she would also sell loose tea, which she confirmed. Definitely give Ana a visit and enjoy the ambience of this unique tearoom.
