Sometimes I feel like a New Yorker at heart, until I actually visit New York and then I realise I am more of a Canadian in New York than a New Yorker, but when I am missing New York-- I like to visit Seniore's Pizza.
It is constantly busy but in a good way. They have a hustle and bustle in an unorganised chaos sort of way and the staff is on top of whatever is happening around them.
You can order take out or stop by for a slice or whole pizza to go. The prices are very reasonable, a slice is about $3.50. The Donair Pizza is a cult-favourite! I'm basing this assumption on the fact that as I waited for 10 mins in line about 20 people ordered it. I got the veg pizza and I love it! I folded it to the perfect pizza "sandwich." and scarfed it down in two minutes. (You guys know what I mean, right?)
Whatever pizza you select make sure you try the complimentary garlic sauce. It's bomb.com! I love the aesthetic of the neon lights, pizza chef mural, stool-seating area and it open lateness (I think past 2 AM). It does get crowded but that's why it reminds of New York and why I will be forever going to SP.
