I don't eat farang food much in Thailand, save the occasional greasy fry up to start the day.
But I was taken to this Italian place last week and it's probably the best Italian food I've tasted in Thailand.
We didn't go until about 10ppm and it was still absolutely ramming; as long as they make the food they do, I can see why.
Enormous "Regular" Pizzas, delicious minestrone, the Pastas are great, in fact the only criticism would be the price and choice of wine selection, but that's more to do with Thailand than the restaurant.
If you like Italian, I'd recommend it. It's al fresco and fans, but has an AC room as well if you need it.
