Not bad at all, 3.5/5 overall. I went to Daddyo's after walking by it a bunch of times and seeing it on a BlogTO article of places to eat around the black hole of food that is the U of T campus. Wasn't exactly sure how it worked at first but quickly saw people ordering their food at the counter and sitting down to wait for their food to arrive. It's a small place so finding a table around noon is a bit like entering the hunger games - restaurant edition. I didn't leave anything at the table I had chosen to mark my territory so while I was ordering my food at least 2-3 groups started to sit down there but the owner was nice enough to tell them I had taken that table already! I ordered the spaghetti and meatballs, it arrived within five minutes and it was about what I expected. Personally, I'm a bit of a purist when it comes to marinara sauce (more tomato, less herbs and spices) and this was full of herbs so I might order something else next time but objectively, it was definitely tasty. The pasta was perfectly cooked as well, just a little al dente. The portions were a little small for what you pay considering the setup (ie: no waiters) and the fact that I had heard this place was supposed to be cheap for students.
Pros:
Quick service
Friendly owner
Tasty
Cool that you can choose the type of noodle for your dish
Cons:
Not as cheap as one might think considering portion size and the fact that there are no real waiters. Pretty much average prices.
Wouldn't rush back here but would be open to going again.
