TL;DR: I love Levetto so much. Their carbonara is literally too awesome to not try! The only reason that this place isn't getting a 5 stars is their lack of space, since they are only able to host around 5 groups or around 20 people maximum.
1. Food (5/5):
Yeah, I find that their house-made carbonara is up their on one of the best I've had in the area. The portions are great for the price (around $10). I've also heard good things about their pizza, but I personally favor pizza with thicker crust (though this is probably the pizza a lot of people favor). Please try try try their carbonara and I know for sure that you will not regret it!
2. Service (4.5/5):
Friendly staff that tell you what's good.
3. Space / Seating (4/5):
The place is actually pretty small located near the West Chinatown in Toronto. As a result, there isn't much seating and you might either have to wait for a table to become available or take your food to go and find some other place to eat it. I would say that they have enough tables for about 5 groups of people, or seating around 20 people at most.
