Why is a cafe so wonderful hidden in a mall on Pitt St?

An absolutely incredible array of wonderful smelling teas, stacked on shelves greet you as you walk in, with a huge collection of beautiful teapots making this small café/store a beautiful sight. A few nondescript artworks and paintings give a nice cosy atmosphere, but of course the highlight are the Teas.
These people are hardcore. Single Origin teas from various parts of the world. Inventive and exciting blends. Cool teapots that (to me) look like little mice. The menu is incredible, with at least 30 or 40 different teas available. You have all your traditional teas, Oolongs, Green Teas as well as many speciality blends, one of which smelled exactly like lime marmalade. I was boring and went for a single origin Ceylon tea which was absolutely delightful.
Lets get this straight. I am a huge coffee geek, and this place has me raving about Tea? It's a special one, and worth searching out if you ever feel like some Tea in the city. The Glasshouse is surprisingly quiet, and a nice place to take a friend to talk over your tea of choice, whether it be Earl Grey, Russian Caravan, or a tea made out of toasted rice and popped corn!
