I've gone to Mother Fool's more than any other coffee place on the east side, mainly because they're one of the few that stays open to 11 pm. (RIP, Escape Java Joint!) It's not exactly my cup of tea, no pun intended, but definitely comfortable and friendly enough. Some of the critical comments below are just plain asinine: MF's prices are no higher than any other coffee shop around, and I think every business has the right to toss a freeloader who comes in, uses the Internet, and doesn't buy anything. (WTF?) True, the Wi-Fi service is a little spotty at times, but it's never been more than a minor annoyance for me. In short, this place is authentic, independent, idealistic, and welcoming, and the drinks are good, and you could do a lot worse than all that.
