We know that F&B are staying somewhere near the C of C on Phillimore St. In the vidcap we see them entering a side door. I believe that the door is on the side of the Old Firestation Youth Hostel, 18 Phillimore St, next to the C of C. Accross the street is a distinctive building which I believe is His Majesty's Hotel on the corner of Mouat & Phillimore.
Building architecture matches both youth hostel & Hotel.
Edited to add: Just found additonal photo of C of C as viewed from His Majesty's Hotel (see 4th photo below). So F&B are standing somewhere between the C of C building and Old Firestation Hostel.
Added additional Google Earth image of where F&B are standing. Note small building behind Old Firestation Hostel. Perhaps that's where the Pleasure Dome room is.
