I've been here before and after the recent renovations -- and while the renovations are awesome (modern decor) and the staff works hard, I still think their dishes are somewhat overpriced.
I recently tried a dish of theirs called "UFO rice" -- and it was such a disappoint. It was fried rice with cheese and definitely not worth its price.
Other than that, their tabletop cooking/grilling is good and their side dishes are decent. One aspect of the restaurant that impressed me was the frequency they would change the grills as you eat -- this was something they did not do before renovations! Thumbs up for that.
Piggy's Restaurant is a decent restaurant, but again, a bit on the pricy side for the quality of food (marinated meats included). A fun place to go with a few friends, but don't expect to be frivolous!
