Best Place for Peking Duck?
Peking Man on Sheppard just east of Leslie on the North side (North York Ikea neighbourhood). It's on the second floor of a medical building. Big red awning with yellow letters. Haven't been there in a while but everything I've had there has been excellent and the Peking Duck in particular is stupendous (done in courses with the duck carved at you table, crisp skin, warm pancakes, fresh green onion brush, hoisin sauce... yum).
If you're looking for "best" as in "quality", then I have no idea. However, if you're looking for "best" as in "most amount of corny fun while eating Peking Duck" I like Champion on Dundas. I don't know why, but I get a kick out of the gong they use to announce the arrival of the duck to your table. :)
Lai Wah Heen (on Chestnut at University/Dundas).
---served in 2 courses: 1) with crepe and garnishes, 2) your choice of duck meat in pastry or stir-fried duck meat with lettuce wrap
---amazing; the freshest crepes I ever had as they cook them table-side as you eat them. They tend to give 2 to 3 crepes per plate. Then won't cook the next until you're ready for the next plate.
---need to order 24 hours in advance
Peak Top Restaurant at First Markham Place (Woodbine/7)
---although they do serve Peking duck, I never actually had it there. However, if their roasted duck is a precursor, then I say go for it. Wonderfully tasty. The skin is just infused with a rich smokey flavoring.
