I know a restaurant in Chinatown sells 烧鹅, unfortunately, I forgot the name... If you come from Bronson (from south), and then turn left on Somerset (towards west), about one or two intersections, you will find this restaurant (with yellow sign and red words) on your right at corner lot. I don't know if they always have it or just sometimes. You can check it out. It is not cheap but for sure it is a lot bigger than 烧鸭. I tried it one time but I didn't find it particularly taste that good in my opinion.
