I don't live in Champaign, but whenever I come to visit my boyfriend, I HAVE to come here (usually more than once). They keep a variety of flavors (my favorites are red velvet cake and original tart), and you can mix and match as many as you like (as it's all pay-by-the-weight). The topping bar includes everything from cereal to fresh fruit, cheesecake bits to mochi balls.
The decour is wacky and fun, and the staff is friendly enough....but the yogurt would make it worth it no matter what!!!
