3 Kings is by far my go-to place for Shisha in the city. I personally have to drive for 20 minutes to get there and it's definitely worth it. My friends and I are regulars there and the staff are amazing. Our Shisha comes perfect every time and the flavor lasts for 2-3 on a consistent basis. If you're in the Scarborough area, I definitely recommend going there and also recommend getting a ice hose with it aswell.
