I just found Harvest Coffee last month. It is a great cozy coffee shop in the Hua Yuan residential area. The coffee is great, the menu is in English, the staff speaks excellent English, and their Saturday breakfast special of Belgian waffles with strawberry sauce and whipped cream, is great. Fridays are college night and the place gets packed, but not a big problem as it is smoke free! (hard to find in China). They also have a small selection of English language books. I recommend the chicken burritos. Their website has a detailed map and GPS grid and can be found at: www.harvest.tianjinguidebook.com
