Love their pizza, but the lady can’t take pictures (lol). I had a hard time getting all my family together, and I’m not in the pictures . She took two, and both came out blurry

I’m probably a bit nostalgic when it comes to this place. It’s good pizza not the best but good enough to try at least once.

I’m sure this place has seen better days. Their shop seems to be too big for the foot traffic they get. Every time we went, I only see one or two people sitting inside, and the entire back area is always empty. So it’s quiet for sure but feels empty… With that said, I only ate here because my bf loves the pizza. I think it’s okay. I used to order the gluten free pizza but since the beginning of November 2022, we’ve called at least 3 times and ordered in person once, and now, everytime they just don’t have any gluten free pizza at all! It’s constantly not available… Maybe I’m the only allergic one around here, but if they don’t make money, they don’t make money. But competitively, there’s pizza places in Chino hills just off grand that do offer more crust selections, and I personally think the pizza is pretty overpriced compared to others. Unfortunately, I can’t go back here if that’s something they have in inventory anymore.

Very clean place. Well maintained. The pricing is steep for the quality and the quantity. Pizza was also heavy on the sodium. Probably not the the best place for the health conscious. Picture is to show how big each slice is. This is a $20 pizza. Each slice is hardly bigger than a phone…..

I don’t know what happened today with my pizza , I ordered a pineapple & canadian bacon today was not the best, totally disappointed , usually I get a lot of sweet tasting pineapple and the canadian bacon, but they skimped.

$30 for a pizza that I won’t even eat and will be throwing into the garbage. First of all it’s an overpriced place. Secondly, just dropping a bunch of veggies on a pizza does not necessarily make it a good and tasty pizza. I’m very disappointed with how awful the pizza tastes. I have been to more pizza places than I can remember. Non taste this horrible. Dominos, lil Ceaser and Pizza Hut makes better pizza than this.

I placed my order with the actual owner, Kris/Chris. She was pleasant, very helpful and spent a lot of time on the phone answering my many questions. I wanted an appropriate order for 4 adults. I thought after I moved here there wasn’t a location within the delivery zone so but I just discovered otherwise. Yeah! We’re looking forward to our order she lovingly created.

First visit. Found this place because of their ad/coupon. Had a very nice little lunch special. Very clean, quiet place. The young lady cashier was very polite and friendly. We will be returning again.

My husband and I went there for the lunch buffet. The girl at the counter was very polite. She asked if there was a special pizza they could make for us. We ordered a half and half pizza. While we were waiting we ate at the salad bar. It didn’t offer much but everything was fresh. We took a slice of the pizzas already there. There were 5 different pizzas out. When the special pizza we asked for was done she brought it to our table. It was piping hot and very delicious. Needless to say we were surprised. We thought she would put it on the buffet. We couldn’t finish it so my husband asked for a box and we took it home. Amazing. The buffet is only $7,99 a very reasonable price. I highly recommend this place.

Their lunch buffet is pretty good, it’s all you can eat from 11 to 2 for just $10. The cinnamon roll stick things are really good. I just wish there was more space to put a larger selection of pizzas.
