Good pizza. It's definitely worth stopping here rather than across the street at the chain pizza place. I don't know the deal with Torontonians' obsession with chain pizza places. At least in this neighborhood you can skip them altogether. Hit a local place and you'll thank yourself later.
Just remember Gigi is cash only. 1 slice = 2 actual slices. That's the culture in this area I guess... Every independent shop does huge slices and charges what would be acceptable for 2 normal slices.
