I have gone to this Chito's Pizza over 150 times (I know because I checked my credit card / debit card bills). I go back occasionally now as this was my go-to spot for shawarma 4-8 years ago when I used to be in the area.
I recommend the $5.00 chicken plate (if you are a high-school student you get a free pop) and the $4.50 pizza with chicken on it (add pineapple ontop of the chicken, it really cuts the grease).
You know a place is a true "hole in the wall" when:
a) the items are called for by its price (i.e. $3 chicken plate, $5 chicken plate, $7 chicken plate);
b) the actual width of the store is no more than 2 meters;
c) they make sales on 'credit' / guarantees that the customer will pay the next time they come in;
d) there is no parking for it - every time I come here I park illegally on the street for a few moments.
The place took a real quality dive when it comes to its food, which is reasonable as they never changed their prices for 8 years. Their sauce is no longer as tasty and their portions are slightly smaller - but for the price, this really can't be beat. This is why I gave it a 4-star review; the quality of the food itself is probably a 2-star to a 3-star, but for how much you are paying, can you really complain?
There used to be a better shawarma shop that was equidistant from Dufferin St. on Bloor St. as well, but in the opposite direction. I think that they closed down because they were probably not turnomg a profit, 1.5x the price and 2.0x the quality of Chito's for $0.50 more doesn't seem like a sustainable business model.
I would caution you from becoming addicted to this place - it is definitely bad for your body. When I ate here everyday for months on end, I gained at least 15 pounds and started getting acne (every time I stopped eating here, I stopped getting acne).
