tried that place last weekend! pasta was over cooked, common honger style vs italian style's chewy texture (al dante (sp?)). but the sauces were good. when i went there for lunch, it was all full and i think i saw leung pui wu there haha
i tried japanese pasta few years ago at the japanese restaurant(on demand st, between robson & georgia). not sure is it still there. they used japanese 汁, i think the same one that they used in sushi and added seaweed. not too much surprise.
