Mr. G's Pizza - Diamond Bar

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!

Always so friendly and welcoming. The food is amazing. They really make you feel like you’re at home. They take the time to get to know you. They know my family and I by name. We have been coming here since before they had the location they are at now. We have had many celebrations here and we will continue to come. We go for the food but stay for the friendly and kind atmosphere.

I’m not from this area. I just picked the one that had the best reviews in Google, I am glad that I did. That has to be the best pizza I’ve had in a very long time. It almost reminded me of the old pizza kitchens from back when I was a kid just great pizza.

I came here for lunch with my friend and we had a wonderful meal! We got the lunch special. 1 small pizza with garlic knots and 2 drinks for $19.95! It was a great deal and it was really delicious. Mr. G and his wife helped us. They were so kind and accommodating. We got a small pizza, half pepperoni and half mushrooms. It was so yummy! My friend had the pepperoni half and I had the mushroom half. There were so many mushrooms on it! I was very pleased. Most places skimp on the mushrooms, but not here. When we left I took my drink to go and Mr. G topped it off for me! So sweet. I'm glad we found this place from Google Maps Reviews. The vibe was really cool too. There is a nice pic of the Venice Canals on the side wall. I will definitely be coming back! Thank you again Mr. & Mrs. G.

I ordered from here while staying at an Airbnb near by. Sam was great he followed my direction well and was so kind. We really appreciated it considering we had a bad delivery with another place. Food was good.
