Glad to see that MDH can have good hot dim sum. My Sat. dim sum experience of 2 years ago was not good. The food was cold and the choices limited from the carts. But I enjoy a modest lunch there on occasion, I particularly like the white chicken which looks like plain boiled chicken but is very flavorful and comes with a ginger green onion dipping sauce, yummy. But order it as a plate, if you are alone, which comes with rice and some kind of green veggie, one time it was sauteed iceberg lettuce, quite good. Also their fish fillets in black bean sauce is excellent. As for the roast duck, I think it is disappointing if you are looking for Peking style roast duck, which should have crispy skin, I believe the duck at Mark's is Cantonese style which is not as crispy, plus in China having fat left under the skin is considered a good thing.
