Nanaimo Information says:
Mambo makes the best pizza available for delivery in Nanaimo.
You can get a gourmet pie with pesto, artichoke hearts, zucchini, and broccoli – or the "hangover", which is very meaty and therapeutic – or there is also the "popper" pizza with cream cheese and spicy peppers, if you can believe it. All delicious. They also have a soy cheese option.
