I've been lurking for the last couple weeks to figure out our dining choices for a whirlwind trip to Toronto, and I gleaned a great deal of great info; just wanted to repay the favor with our choices and observations. Our priorities were cheap eats including especially great Chinese food. We wound up staying in Markham, so it seemed to make sense to spend one day there and one day in Toronto proper.
Favorites - we *loved* Burger's Priest (on Queen St. West) - two of us shared a High Priest burger and found it really well made, perfectly seasoned and cooked. I had read reviews that noted lackluster fries, so instead we went across the street to Banh Mi Boys and had the kimchi fries. I really enjoyed them; DH thought they were fine but not necessarily incredibly special.
We also really *loved* Beast - went to happy hour (aka Beast 120.) Had a dozen oysters, the pork belly and fried pork skin (DH loved it), cauliflower with pimento cheese sauce, doubles. Really great. Surprised they weren't more full - we got there at 5, and when we left around 6:30 the outside patio was full but still room inside. Will need to come back for brunch the next time we visit.
In Markham we went to Richmond Court twice, mostly because we needed somewhere decent late at night. First night we ordered suboptimally - the wonton noodle soup was decent but rice noodles with pork and veggies were average at best. Second time we got a special of pork with Chinese broccoli (gai lan) which was tasty and huge, and stir fried rice noodles with XO sauce which was great, with lots of wok hay. So all in all we were quite happy.
We really liked Sam Woo BBQ restaurant, which was recommended by a friend. The roast pork had lots more depth and complexity than what we're used to in Boston. We even came back that night to get some pork to go, but the 11pm pork was not as great as the tea time pork, not surprisingly. We still ate it all though.
We really enjoyed our all too brief visit to your city and hope to return soon!
