I recently had the chance to sit for a few stolen moments at a cafe (Stone Cutter's) and enjoy a cup of oolong tea. The cafe did a fine job with keeping the brewing process easy while giving me loose-leaf tea! It used in-mug brewing filters. I like this method because: 1) I can control the steeping time myself 2) I can use the leaves more than once 3) I get higher-quality teas with the loose leaf and 4) It's pretty. I hope other coffee and tea shops give this a try!
