Location wise, as others have said, future MRT next to it.
If you drive, just a little further down, it's TPE and PIE for access to Pasir Ris, Ponggol, Jurong etc. If you head the other direction, there's ECP at Xilin avenue next to Expo.
The area's quiet most of the time except for when Expo has SITEX, Natas etc at the same time and during evening, the other side towards TPE/Loyang will be jammed.
Beware the overhead bridge just after Expo towards Tropicana though. Hidden camera during the day most of the time.
The Shell's your minimart if you're lazy to drive out for groceries.
