When you've got someone with a big appetite and need a reasonable price with which to feed them, Green Olive is a pretty good bet. The restaurant itself is pretty casual, complete with checkered picnic-esque table cloths. On the walls hang some Italian-style prints on canvas that you could pick up at your local home decor store, but they match the rest of the restaurant, so it's all good.
I ordered myself some linguini puntanesca-prosiutto, mushrooms and a cream sauce. I believe the dish was $10.95. It's by no means the drool-worthy plate of spaghetti I once had in Italy, but decent food nonetheless. It's the kind of place I'd probably take my parents. They grew up in small town Saskatchewan. They'd be comfortable here.
Location is pretty easy to find, just hop on Hwy 1 and exit at 68th St Northbound.
