Not everything is consistent in quality - some bland pasta dishes - the curse of roadhouse venues - but interesting pizza and other menu items not found on most other mass market restaurants. Bright, colourful atmosphere - a fun place for kids, the ideal family pitstop.
Service is usually pretty slow and it's not uncommon to hear the staff cursing and yelling at eachother back in the kitchen.
I've had the pasta twice, and both times I spent the night in the bathroom afterwards revisiting it.
The pizza is awesome, though. As long as I have that, it seems to be ok. Miss the ravioli bites, though.
