Interestingly, Singha is one of the best value beers you can buy in the UAE licenced stores. Yesterday I bought a pack of 12 cans each of 490ml, for AED 75 (which is about THB 726 at today's rates).
Cranking the numbers that makes 12x0.49=5.88 litres for THB 726,
Ie THB 123.5 per litre.
Not a bad deal at all, here in Abu Dhabi!
