Food was really good and great portions for the money. Menu has a ton of variety! Service was very fast and food was hot of the grill. I would say this is the best available place close to the ontario airport! I had the Cali Burger and my son had the Carne Asada quesadilla (pictured).

JJ Grill is a great "hole in the wall" diner/restaurant. They have a diverse menu with just about everything you can think of for the pickiest of eaters. We ordered; bacon burger, chili fries, teriyaki chicken and fries, and a breakfast burrito. Everything tasted delicious, portions were very large, too. Service was quick and the people working the register and behind the grill are very friendly.
