Any Dim Sum with Carts near Woodbine and Steeles?
Ginger & Onion in Market Village has carts. Cheaper than Dragon Dynasty, quality is ok, different clientele - more grassroots type of folks.
Very Fair Seafood Restaurant in Milliken Square (Milliken & Finch). Again very cheap, ok dim sum, you get what you pay for. I prefer this over Dragon Dynasty as I do not like how DD differentiates between regulars and the rest of us (regulars wait in a separate line). For me, the difference in quality does not justify the premium in price and the poor service I experience at DD.
if your client does not speak Chinese, these places may be more of a challenge but maybe also more adventurous.
