I've been a fan of this coffehouse for many years. It lacks some of the comfy characteristics of some coffee spots (i.e., no sofas, big chairs) but I think that's because they would rather accomodate more patrons. It can get pretty crowded and noisy at times.
What I love most is it's location. It's a great rendezvous spot after spending time at the art museum or botanical gardens. Sitting at one of the outdoor tables provides a nice relaxing and serene feel.
