It's a place to hang out and have dessert with a special someone or a group of friends. The food and drinks are expensive relative to their base cost at a bakery or whatnot, but remember that you're paying for the privilege of sitting in the lounge.
I was there for a brief hour and didn't get to see different aspects of the cafe (such as board games and other things), but I found the decor and general environment to be good. I did feel the couches were a bit uncomfortable though, being too soft and easily sinking into them.
