Mr. G's Pizza - Diamond Bar

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!

By far the best pizza in the area. I live in Chino Hills and routinely make the drive over because it’s that good! And not only the pizza. I have tried a few other menu items as well like the mozzarella sticks and so far have not been disappointed. Highly recommend!

You need to secure the bag. The delivery driver spilled the spaghetti sauce because he carried it tilted

My family visited this pizza during the week and we were greeted by this man and we felt welcomed the pizza was so good even the crust had like garlic oil at the end of our dinner the owner came by with cookies 🍪 😋 like who does that only people that actually care for his customers.

Great spot to hang out and enjoy good quality pizza! Ordered here a few times and the pizza never disappoints! The owner Sam is such a kind welcoming person. He greets you with a friendly smile. Mr. G’s pizza always hits the spot! Definitely recommend

Great friendly staff and awesome food!

Amazing pizza, awesome service and great atmosphere. Thank you everyone for the hospitality and the yummy pizza!

Been eating here off and on for 25 years. The food had really better over that time.

Delicious food here would definitely come here again. I highly recommend this place. Outstanding customer service family owned

We had a great meal at Mr G’s! We were a team of 20 and were able to reserve the “party room” online. No need to wait for a table. Great, family-run restaurant. We had the kids order individually on one tab, but they had an ability to take individual orders too.

Food came out quickly and efficiently! Would highly recommend the calzone! But all of the dishes went down well for our athletes. Will definitely come back next meet! We appreciated the classic family-style vibe of Mr. G’s, thank you for accommodating our team!

Mr. Gs was AWESOME. Such kind staff, food was great. I tried Mr. Gs special pizza and the Alfredo shrimp pasta, I would definitely order again. I came in a group of 25 and the staff was very patient, accommodating, and everyone received food swiftly. There was not a dish around that I wouldn’t eat.
