There's almost nothing in the neighbourhood that competes with Papa Chang's for fast and filling cheap eats. It's a small place that fills up quickly during lunch and dinner hours, but it's never a long wait to get a table. Of course, this isn't the place to go if you want to take time and savour your meal, unless you visit at off peak times.
The portion sizes are reasonable for the price, and tastes fine. That's really it... Papa Chang's has neither the worst nor the best Taiwanese food I've tried, and neither the best nor the worst service. The speed and prices are what keeps me coming back, especially comparing against other restaurant choices close by.
