Despite it's name (which gave me moment for pause when deciding if I wanted to check it out), Xtreme Bean is a hip coffee house with a college feel (they even have a "study room" with quasi-cubicles that is ironically placed in what used to be a bank vault). Further, for those of you that spend hours on end in coffeehouses, THEY HAVE FREE WI-FI :-D
The "coffee flavored coffee" and tropical ice tea are good (I personally tend not to stray into more interesting coffee drinks, so you'd have to check those out yourself) and the entire selection of both food and drinks is very reasonably priced (compared to corporate coffee).
As of this post, there is ragtime piano on Monday nights as well as performers on the weekends.
They have a drive-through window.
Oh yeah, they don't appear to have updated their website in quite some time... most importantly, their hours of operation. The website says they are open 24-hours on the weekend... but I *think* they are closing at 1am in the summer.
EDIT: Go for the pumpkin muffins... they are most excellent.
EDIT 2: Due to the recent rise in popularity of this coffeehouse, I can no longer get my beloved muffins as they all sell out long before I arrive at night. *tear* Oh yeah... and all the employees probably think I'm that crazy muffin guy. *shrugs*
EDIT 3: I'm officially downgrading my review from a 4 to a 3 as it's now difficult to get a table indoors and I have no interest in sitting in the smoker's lounge which is their patio area. *sigh*
