Kings Cross Environment 
FYI – The eye sore that was the BP station on Goods Way is history!
Thanks Tony for correcting me, BP was the only place I didn’t go to take a pic – already corrected.
The Hurricane pool and snooker club under the Scala is open 24×7. You have to be a member but they offer daily membership for £3.
James thanks, I added it in behind the Scala entry. Wow, sounds like a feature in its own right? Any chance for a report with pictures about this corner at Kings Cross unknown to some?
Glad I asked, thanks for posting Daniel.
I don’t know of any Cost Cutter Convenience Store on Euston Road. There are two or three convenience stores the top end of Grays Inn Road which are open all night. Perhaps you are getting Grays Inn Road mixed up with Euston Road.
kxwalker At the point were Euston Rd. merges with Grays Inn Rd. there is the Cost Cutter near the bus stop for West bound buses. But we are literally talking about a distance of plus minus 20 meters on a merging street bit that decides where Euston Rd starts and Grays Inn Rd. ends. You are quite right to insist on correct detail, the truth is I was not clear where one starts and the other ends. Apologies for failing on that and many thanks for your clarification.
The Co-op garage is open 24 hours on Caledonian road
