It seems a popular choice for weddings too and I'd say for banquet food, it is really decent. I'd love to be back to try the other dishes!
Pekin have roast suckling pig on the regular menu, so walk in customers can have this without pre-ordering.
Overall, this is a superb restaurant. For me, I will avoid the peking duck, as there are plenty of better examples of this art around (the Imperial Treasure Super Peking Duck in Paragon is the grandmaster of the art). But the seafood is fresh, expertly cooked, and tastes superb...all for a price you cannot get in Singapore.
