Correction, if there's anyone looking at this thread for directions on where to get a gas cylinder for BBQ or cooking, the place referred to in Baldrick's previous post does not sell gas cylinders or fill gas cylinders.

I did find a place, simply by driving around & asking in several shops.

I bought mine for QR 275 full of gas.

Location is in Al Mansoura opposite the intersection with Al Rawdhatain. But I did see two others driving down the length of Al Mansoura.

He has the new bottles ( large & small ) plus will fill while you wait.

There's a piece of carpet spread on the footpath outside. Drive your car onto the pavement along side & it's a "drive-thru"!
