The environment and food makes this place quite unique in Toronto and not something you can find elsewhere.
The meats were cooked perfectly both times I was there: medium rare with a solid char on the outside. I actually didn't think the meats were that salty...However, I stayed away from the buffet and stuck to salad. The service remained prompt and I didn't feel like I couldn't get enough steak.
For the price point I'd say it's worth it. At a normal steakhouse, you'd get a normal steak dish for ~$30-$40 easy. So, $50 doesn't seem that bad for the AYCE (not cheap but not outrageous). If anyone is new in town, I wouldn't hesitate to bring them to Copa.
