I've been in several times with my girlfriend, as we're both fans of their mini-cookies and shortbreads. Our favourites are the acorns (acorn shaped shortbread dipped in chocolate and toffee, like a Skor) and the jam centre cookies.
I've also tried their macarons, which have been hit or miss. I've had really stale Caramel ones which were greatly disappointing considering their price, and deliciously fresh ones like Passionfruit and Wildberry, which were heavenly.
I am taking my rating down a star due to their crappy service. They have the same two-three women in there that get flustered if there are more than two people in the shop. They get annoyed, they give attitude, they don't know who to serve next. I am not a high maintenance customer either, I know what I want and I am polite. I don't know if they are the owners or the bakers, but either way if you are going to serve people at least treat them respectfully.
