I have eaten here three times since my first visit in March. And what I always say is repeat visits means the food isi CONSISTENTLY delicious.
That's special in a city that is overwrought with let-downs. My latest visit to Khao was as good as the first. It's still just as busy, but they make the effort to fit you in as soon as they can. We were told it would be a 15 minute wait so my friend and I went for a walk. About 20 minutes later we returned to find a table waiting - 'reserved' - that's right, they didn't just give it up to the next group. Service is a little slow but forgiveable. And the food, still SO good. My favourite is still the Gaeng Graree, spicy yellow curry with beef. It's amazing how so few ingredients can generate such big bold flavours.
Slow and steady wins the race, flashy and pricey fizzles.
