I'm landing on a 3.5 for this one. Had a problem deciding between the two but then thought, when would I realistically come back again? and since the answer was probably not in a long time, I settled for a 3.
This place has always been somewhere I've been meaning to try. I am physically reminded of this place on a regular basis since I live further up in North York and drive past Miller regularly.
What Miller has going for the restaurant, is that it is in a great location. Decor/menu/price/quality-wise, I'd probably compare it to one of the chains (Moxies, Baton Rouge...) and food-wise, it only scores a little better.
We went on a Saturday night and found the crowd to be in the 50-60 age range. I think that sums up the place pretty well though. It's a place that hasn't changed much, has been there for a long time, and doesn't look like it'll change in a while.
