Our first clue is the image of John Cheung waiting patiently outside with a sign behind him saying 'Chow Bar Kee'. As luck would have it the business as well as the building is still around - this is the Mody House on the southwest corner of the Blenheim/Mody junction, which puts John well and truly in Blenheim Ave.
The next two shots are less helpful despite the Manna Korean restaurant showing us an address on 32B Mody Road. It turns out that the B refers to the fact that this small business is actually behind number 32 Mody Road, even though its front entrance is on Blenheim Ave.
Not to worry, here is a recent Streetview (captured in 2009 because it was the clearest picture) which shows that the girls were running out of the Lyton Building entrance. The Manna Korean Restaurant was located in the shop with the black front and as you can see the entrance the girls run from has since had some brown tiling put on it.
Of course the clincher though was the next shot which shows our chasee (is that even a word?) running up Blenheim Towards Mody and the junction where several roads meet - Hanoi Rd, Hart Ave, Mody Rd and Blenheim Ave all meet at the odd junction. Look at the background below and you will see the building that used to sit between the meeting point of Hanoi and Hart. We've seen this building before and regular readers may remember it from Bloodsport a while back. Coincidentally, the Bloodsport scene also involved a chase on foot.
