I've eaten at Greenwood Smokehouse BBQ once, and ordered from it once. The first time we did take out I had a poutine, and the pulled pork sandwich. The sandwich was good, but the poutine was a big disappointment. The fries were bad, and the cheese was hardly melted. We decided to give it another chance because we had done take-out so we went for sit-in.
When we ate in we shared the pulled pork sandwich, which was once again good, and also split the Black Angus Burger - which was OK, but not compared to the pulled pork.
The pulled pork is pretty standard (which isn't a bad thing, it's just not better than everywhere else).
With a relatively limited menu it doesn't make it easy to warrant going back again unless someone is going specifically for pulled pork.
