When I walked by this place the first time the ambience was intriguing, and it is an excellent concept. It took me three months to get around to finally going there.
The overall strength of this place is the ambience. Part of that atmosphere, by the way, is fellow patrons oohing and aahing over whatever it was that you ordered, so don't go there if you have privacy issues. But the lighting, chairs, interior decor - all fantastic.
The service was technically slow, but to be honest that's just fine as in a place like that if you're hurrying then you're missing the point.
That said, my wife ordered the "white hot chocolate" and I had a chai. The chocolate was oddly presented - in a martini glass - and tasted essentially like a melted chocolate bar. It may have been that, in fact, as it was also quite a small serving. The chai was not even, I'm afraid, as good as something I'd toss off at home.
I really, really wanted to like it. I tried. The desert, by the way, was good. A good, solid, unpretentious, benign "good." It was like the...Lexus...of desserts: essentially higher-average quality presented in a top end packaging. If you'd had the same dessert at White Spot you wouldn't have said, "what is this doing here!"
