Beside the main purpose of Shell i.e to fill in the fuel, it has other good facilities such as convenient shop "Select", separated Surau for men & women (with Sejadah & Telekung), toilet, etc.
Careful when filling up here. I just had a bad experience. Gave RM 50 but fill only 20. Then had to wait 10 minutes because they checked the cctv to make sure that i gave 50. Bad service.
