A friend of a friend opened this place whilst also owning a Vietnamese restaurant in Paris. I suppose that doesn't necessarily mean it's good (there are many substandard pho places around the world and the Viet restaurant in Geneva left a lot to be desired...) but given the French influence on Vietnam (read Indochine for more), they must have at least a partially discerning palate.
It's difficult to compete with all the cheap similar clones on Victoria Street, so good on them for being a bit different and having more Northern and Middle/Hue dishes.
The highlights for me were these three:
Four treasure salad $14 - green papaya with grilled prawns, mango salad with grilled fish, grilled apple salad with grilled beef, grilled chicken with shredded cabbage. There's so much variety here to easily be a full meal.
Beef campfire/bo quanh lua hong $24 - overcooked beef but made up for by the lemongrass marinade and combined with other ingredients to wrap in mini rice paper.
Lau Canh Chua & Ca Kho To $65 - I expected a big sized canh chua ca (catfish usually or in this case barramundi cooked in a sour tamarind soup) but it also came with claypot grilled fish, a classic savoury Vietnamese fish dish. The combination of the two is well enough to feed several on its own.
The cut up rice paper rolls were a waste. The signature Dac San Bonjour Vietnam of prawn tempura, zucchini and crab or fried bread crumb squid was ok. The grilled rockling with dill is a Vietnamese/French staple and quite good although the fish was very thin and so heavily cooked. The fried noodles were rice noodles rather than expected egg noodles and the dish wasn't that good.
I would stick with the top 3 for next time. Order carefully - it's easy to over-order.
