I noticed a new Starbucks at Wall Centre yesterday. This is just across from the main entrance to St. Paul's Hospital. I just took a quick pic whilst standing out in the middle of the bike lane and I didn't manage to get a good angle on the sign (it's on the corner, sticking out at a 45 degree angle) but trust me, it's a Starbucks. It looked like they were just setting up.
