If you're into heat, this is the pizza place for you.
I can only comment on Pizza Boys' food as I haven't actually been in the establishment itself, but I have tried their mutton pizza and can confirm that it's really good. The mutton is where the spice comes from. Being a guy who's only starting to delve into spicier foods, this was perfect. It wasn't too hot, but yet it still packed a punch.
I also really like the spicy dip that they sell for their pizza. Usually pizza dips are creamy and mild, but not this one! This dip was packed with chillies and other spices, but it still had good flavour.
I'm a big fan of Pizza Boys cause they fill a food gap I never even knew existed - spicy pizza! Will definitely try to make a visit if I'm in the area.
