I went there for winterlicous lunch with coworkers. http://www.toronto.com/articles/bar-buca-winterlicious-menu/ For $18 I got 5 plates.
Food (4 stars):
Appetizers:
I got Testa (crisp pig's head with a few spices): 5 stars - very delicious
I also got Nodini (bread knots with rosemary and garlic): 3 stars - nothing special
Main Course:
Nero Di Seppia (Quaid in ink with king mushrooms): 4 stars - it was good, I chose it since it was the only option with some meat.
Desert:
Cannoli Siciliani (5 stars) - amazing tasty
Torta Cioccolatino (4 stars) - good, but cannot compare to Cannoli
Service (5+ stars):
Very friendly and proper staff. Very polite and knowledge about the food. One of the people I was with was vegetarian, and the waiter came back after the order to let us know that Cannoli Siciliani is baked in pork fat, and asked if he wanted to switch the order.
The staff was always present and was refilling our water glasses on regular basis.
Atmosphere (5 stars):
Very cozy. The place is not very large, so it is not great for large groups, but great for a few people to talk over small bites.
I would recommend it for a place to catch up with people.
