This is one of those places we return to, either eating in or take-away. I haven't been to Vietnam, but the food here is very good. Seems to be a good mix of Vietnamese and Thai food, with a menu that isn't overwhelmed with myriad choices. Can recommend the squid in batter, which is light and crispy; the pork in five-spice, which is rich and filling, and the aubergine side dish, which complements the mains very well.
The service is very good. Huong is attentive and friendly without being overbearing. As a sign of the food quality, I have often seen local restaurant owners eating there.
The food appears to be at the higher end of the price range, but many restaurants recoup costs through alcohol. Viet-Thai is unlicensed, but the free corkage still keeps an evening out on a budget. Three courses for two with coffee is less than £50.
