The food is ABSOLUTLY amazing. I am a big sauce person, and their sauces really top everything off! Fresh ingredients and flavorful. I catch myself craving it so often LOL. The breakfast burritos are bomb also. Def a must try!

The place is hidden and it can get confusing trying to find it; however, the food and service is amazing here.

I was very impressed by the selection of different meats. Not only do they have pork belly and shrimp for their bowls, they also had brisket, which was amazing. The service was awesome also. They walked me through the whole process to make a bowl. I've been telling all my coworkers to check this place out. 10 out of 10 would do it again!

If you haven't tried it yet I highly recommend grabbing lunch at the Fusion Grill on Guasti! This place has very chill vibes and the service is spectacular! Shoutout to the Cook/ cashier Patrick, he really knows how to chief it up!

Friendly service with flavorful food. This place is the Chipotle of Asian food. They have a base of either rice or noodles, I prefer the rice. Then you had some veggies, and they were actually nicely roasted, and not mush like many places tend to overcook. Then you had the proteins, they let you choose all of them, you just get smaller portions if you choose each one, I enjoyed the shrimp, the sig sig, which is pork belly, and also got the chicken as well. A nice variety of sauces topped it off. I enjoyed the green sauce the most. Get the little crunchy noodles on top. It's a cute little place, and I would definitely recommend going!

I can see how this place doesn't have as many reviews based of sheer location. That being said, stay away so it stays a secret and I don't have to wait so long because I WILL be back lol. So honestly this is a hidden gem, the ambiance was wonderful from the service to the lay out of the restaurant. The part you've been waiting for. The food. Wow. Just wow. I got the breakfast burrito, and this might have instantly shot up to first place. Idk I'll have to try it again to confirm. Hopefully the system doesn't glitch this time. That'll help em remember

Found an amazing hidden jewel of a place! Outstanding! I cant wait to go back and customize my next bowl.I customized a bowl with rice, umami noodles, and a variety of fresh toppings. Then i added some of the unique sauces.....and man it was a flavor explosion.The staff was friendly and great, the environment was nice and relaxing, and this place has everything you need for a great meal to a quick snack.They are open for breakfast and lunch... and am looking forward to going back this week and trying something else.Vegetarian options: You can create your own bowl the way you like. They have many great vegetarian options.

This place is in the cut of all the building and would have never found it unless searching on Yelp and I'm so glad I did this is one of my favorite go-to spots now. I'm continuously bringing my classmates along with me to eat now. The service is amazing here, the staff is always extremely helpful and patient especially if it's your first time. It's a chipotle style set and you can build your own bowl or tacos. Everything is full of flavor and cooked to perfection. The sauces are so good I like to mix and match them. What I love the most is I can build something healthy to eat based off of their options. 10/10 recommend.

I work in the area and ate here for the first time a few days ago, and it was SO SO GOOD! I will definitely be back every week!

I have tried and recommend their tacos or bowls. Tri Tip or Chicken proteins are flavorful and you can taste the "grill" on them. Marinade is yummy on the tender chicken. The wood fire taste on the tri-tip, *chef's kiss* You can't go wrong with either one. Base for the bowls I get either Fuze rice, Chimichurri Veggies or Seasoned Potatoes. Toppings = just add them all! Sauces = all are good but I believe I get the green colored one. I have yet to come to this location but have used Chef Fred for my son's 5th birthday with Califuze catering and looks like it's the same type of food. All of my guests raved on how tasty the food was. One even went up to me and said "Joy!" Pointed at his bowl and said "are you serious?!" and continued to say how amazing the food was. It's so tasty that you forget that it's also surprisingly healthy. Happy for you Chef Fred in your newest endeavor! I wished you were much closer to me because I would go to your place all the time! Can I propose a location in the South Bay? :)

Tri-tip is so good. Got a bowl and its a bit like a chipotle bowl but better. Easily 5 stars

Omgosh, this restaurant is DELICIOUS!!! Thank you for being a vender at our high school football games in Chino Hills!! My husband and I are avoiding carbs, and we got our tri tip bowls without rice/noodles--just all the meat and veggies. It not only tasted fantastic, but we were very satisfied. We will definitely be visiting your restaurant regularly!

Amazing food and service. It's like a Cava but way better and fresher. I was able to mix up my bowl and try the chimichurri veggies as well is rice and some umami noodles with tri tip. Amazing flavors and the quality was even better. The price was extremely reasonable too and we had some delicious banana bread pudding samples that were delicious ! Def going back asap.
