Can you ever go wrong with deep-dish pizza? First time trying this with friends, got two large killer kings, one with mushrooms/green peppers/steak, other with mango/pineapple/bacon/chicken. Shared this among 5 people and it worked out great - $12 per person and you will be full.
Get the chipotle sauce for the steak pizza, amazing combo. We got spicy sriracha for the chicken one, and it was a little too spicy..
Atmosphere is nice, but the place is small (seating for 15 cramped). Wait is long (30-40 minutes) but worth it! Definitely recommend for Mississaugans :)
