Mr G's is the closest pizza joint to Chino Hills at the edge of the Diamond Bar border. If you live here near Stater Bros in Chino Hills your closest options are not as good. Really friendly staff that had it hot and ready when I got there. Tasty pizza that feels special rather than chain pizza places. It's a little pricey but what isn't these days.

Always so welcoming. The Korean pizza is absolutely the best and Sam is the kindest and most welcoming guy ever. Always a pleasure to din in or pick up a pizza.

My son and I ordered a pepperoni pizza for movie night, and wow, was it good. This is the FRESHEST crust I've ever had on a pizza, simply outstanding. The sauce was rich and flavourful, and the pepperoni was perfectly crispy with just the tiniest kick of spice. The pizza arrived piping hot, and with very friendly service - If I'm not mistaken, the owner himself delivered our pizza to our door. We will definitely be trying their other pizzas soon!
