Even the original restaurant in BKK uses canned crab meat. The restaurant does sell the can of crab meat if you want to buy it.

What matter is who cooked it. In BKK, Jay Fai still cooks the crab omelette herself. In Malaysia, dunno which chapalang chef cooks it. That's the different, apart from the price which is double of what original restaurant is charging. Hahaha.

Better just fly to BKK to eat it la.

The one featured in the tayar man guide is main restaurant in BKK or KL branch?

Ahhh.. ok.

Anyway, what does tayar man knows about food? I wouldn't trust any food review done by a tayar man.
Basically if you pay enough money, you'll be in the guide.
