Went on a Tuesday and they have hard and soft beef tacos for $.99, a great deal. Lunch for $5 when you combo it. I love the mexi fries as they have a great hot sauce to dip in. I've tried other items such as the burritos and the owner will sub out sour cream for guac. Fast service and very efficient. It's in the mall so ambiance is the food court which is pretty clean and comfortable.
I was at Park Royal on the weekend, went to Taco Time many times before and ordered their Soft Chicken Taco combo with mexi fries and soft drink.
Although I found the price high, my meal was filling, had lots of flavour, and couldn't finish my taco, it was that good.
I find the staff friendly, food court ambiance and quick service. Will be back.
