Like Mexican food?
Well this is as authentic as you are going to get in Whitby. The food was very tasty, the portion sizes are insane (good thing), and the staff is very personable. If you want it a bit spicier, then opt for the Diablo sauce on the side. Not offered on the menu, but it is apparently the way to go. The hot sauce packs some heat as well as flavour.
The place is much larger than one would expect from the outside. If the place looks busy, still give it a chance, there will be room.
