It took me almost four full years at CWRU before I finally made myself go here. I now consider that previous time to have been mostly wasted. The food and drinks are frill-less, but plenty of options ensure that everyone can find his cup of tea (sorry, it was unavoidable) or baked good (cookies, pies).
The real allure is the totally unique ambience. The tables are made from logs. Board games abound. The mugs are hand crafted pottery. The tea strainers latch onto the side of the mugs. The baristas (baris-tea?) are liable to play Scrabble with regular patron in between brewing up tea.
No table is the same, so you'll need to choose your seat wisely. My favorite (so stay away from it) is the wavy reclined seat toward the back. Great for reading and/or a nap (only if you're a decaf drinker).
