When I lived on Dundas I always used to walk by Hong Shing and be shocked that it was open. 1 AM on a Monday, 4 AM on a Saturday, Hong Shing is always available to cater to your hunger needs.
It's honestly not anything gourmet, and I don't think anyone would expect it to be. Yet I still find myself craving a special from Hong Shing every now and then. It's either after a long night at a bar, or when I only have seven dollars cash and want something delivered. Yes that's right, cheapest delivered food ever.
The General Tso's chicken is about as "americanized" as you can get when it comes to Chinese food but it's still delicious and a generous portion. For five bucks you can't go wrong!
