I heard this place has some of the best burgers in the GTA. So, I went ahead and ordered:
NEW YORK'S FINEST TAXI SERVICE.
This is a cheeseburger with G14 sauce, lettuce, and tomato.
It tasted like a typical cheeseburger with lettuce and tomato. The G14 sauce looked like a mix of mustard and mayo. The ingredients were also pretty fresh. Wish I ordered something from the secret menu, as I didn't find this burger very special. It's definitely a bit better compared to other fast food burger joints.
Side note: A man rushed into the store, swore and yelled at the employees about the garbage cans being full and not thrown out, and then pushed his way into the kitchen. I assume he's the manager at this store. As a customer sitting and trying to enjoy my food, I was quite frightened. Shortly afterwards the employees started to tell customers that they're closed even though the store hours say they're open till 9:30. After seeing the manager, I wanted to leave anyway. I wouldn't mind trying other Priest burgers in the future but I'll likely go to a different location.
