(2 1/2 stars).\n\nDon't get me wrong, I love hanging out here and have been doing so for a while. It's a unique spot and has a kind of awkward-but-homey feel, like it's housed in a building it's not really supposed to be in. The vibe is upbeat and friendly for the most part and it's kind of cool to hang out in a VAULT. But the two-star rating comes from the most important reason why I'm here, yo: the coffee.\n\nI have never once had HOT coffee here. I like my coffee searing hot. Like lava. But I always get flaccid, limp, lukewarm beverages here. I even specified \"extra hot\" once and it still wasn't up to temp.\n\nBut the tea selection is really good. I like how the loose leaf is presented in a way that you can see the contents of what's in the tea blends. And the pastries always look very tempting. There's a lot of fun, zany stuff on the menu, but I have the coffee tastes of an old man. I want it plain, strong, and hot. XB seems like it may be more geared toward providing caffeine bombs pumped with sweet stuff for students pulling all-nighters.
