Love the taste of the herbal duck. It's not overpowering for those who don't usually like the taste of chinese herbs. The bbq pork (or char siew) is worth trying too. You can also order other dishes pretty much like a chinese restaurant, so I usually order a vegetable stir fry or soup to go along.
The old ladies taking orders and serving are nice and friendly, and would be happy to offer suggestions.
Some road works that is taking ages is going on, so that makes the walking from City Square to the coffeeshop slightly difficult. Look out for the big hanging duck outside. Hard to miss once you get on that stretch of road.
Oh, and this is near the cluster of hip cafes, so you can grab coffee and dessert after a satisfying ducky meal.
