I haven't been coming here for very long, but so far I really like it. I don't drink coffee, so I can't speak to that, but they have a decent tea selection (some loose leaf, some in bags) plus Izze sodas, which I enjoy. They have a vegan fruit bar which is delicious and a great accompaniment to a mug of tea.
I think it has a reasonable amount of seating for the size. I've never been unable to find a spot to sit, even though I generally need an outlet for my laptop. I've also only had trouble connecting to the wi-fi once and when another customer told the staff she was having difficulty connecting they re-started the router for her right away.
I love that they're open late - until 11, as there aren't many places around here that are, and I've never been made to feel bad for staying for a while and enjoying my beverage.
