Too high price for the food and service offered.
Food/taste: not bad, but they still need to improve the consistency of the cakes a bit so they don't get crumbly. Overall, it's OK, but nothing surprising.
Staff/service: the staff is lovely and tries very hard to provide good service, but they haven't tried practically anything on the menu to properly educate customers. Step #1 of having a restaurant: have a trained staff of servers who have, at the very least, tried what's on offer.
Adding both points together, we arrive at the VALUE/PRICE of the items. I don't know what math they're doing because they have more expensive ingredients, but it's completely unrealistic. Even more so when you leave there with Styrofoam packaging inside a plastic grocery bag. If you want to sell yourself as a brand of exclusive items, the entire experience has to convey that purpose to justify the price charged.
Unfortunately, I won't be going back and I don't recommend it. There are other gluten-free bakery and pastry shops that are more honest in their offerings in Brasília.
