Affy's Premium Grill is pretty much the best non ethnic Halal joint in the GTA. Of course, in the context of the GTA, where pretty much every Halal place is ethnic, a traditional western style steak place like Affy's would count as 'ethnic'!
Pickering is a ways off from where I live, so my wife and I make our trek to Affy's a big adventure, which we treat ourselves to every couple of months.
I've tried a number of their main dishes, from the Filet Mignon, to the Chicken Pasta Primavera, to the ribs. And all the fare I have tried is superb.
The Filet Mignon is just heavenly - tender and juicy. The ribs are great as far as ribs go, though to be honest, I am not a fan of ribs anyway. I'd rather just have the steak! The Chicken Primavera is also great - the spinach flavour really stands out.
Affy's is also a great family environment (perhaps a little too much so?), and you will see lots of folks with kids tagging along, enjoying a nice night out.
To summarize, Affy's is by far the best non-ethnic Halal restaurant in the city, and I highly recommend people to make the trip, even though the Pickering location might deter them.
