Literally so good! Such generous portions for the price. The quality of the food was excellent, the service was great and quick, and it tasted authentic! The chicken katsu was perfectly cooked, the udon was actually thick and perfectly cooked and the sauces and Mac salad were so good. Highly recommend! Also, the Japanese curry was great!!

Great place I discovered in upland next to sprouts! This isn’t the biggest place, but there are some seats inside if you do want to dine in.
What I like about it is that they make it simple, you order a base, a protein, you order a sauce and it is $15 just like that. The katsu was crispy and the beef was tender. The macaroni was made different, and wasn’t just packed with mayo, so it was quite good.
If you are looking for katsu in this area this place should fit the bill. Until next time.

The chicken katsu was delicious! Crispy on the outside and very tender in the inside! I got the plate and everything was fresh and delicious! Loved the macaroni salad! The women working there were kind and accommodating to their customers! I will be back!

Absolutely delicious! I just grabbed takeout for the first time. The gentleman working the front was nice and helpful. I ordered the Chicken Katsu Plate which came with miso soup (good) and I chose to have rice, house salad and macaroni salad. I also picked the Very spicy sauce (nice kick, very fresh tasting) and the Pear Curry (amazing, sweet and savory). The Katsu was perfect, crunchy without the meat being dry. The house salad and dressing were a perfect compliment to the rich Katsu. I did also order some pork Gyoza which were also very good. I can’t wait to go back and try some more sauces!

A quaint, food spot with amazing sauces! I had been craving Japanese curry and was hesistant to try new places. I was pleasantly impressed with their Japanese curry + chicken katsu bowl. It reminded me of the takeout I had in Japan. On top of that, the customer service from the owner was amazing. She gave us samples of her other sauces (basil, tonkatsu, and sweet chili). All were amazing. Other pluses: clean bathrooms and tables, lots of parking. We paid about $24 for two bowls, and a soda. We would definitely come back again!

This place was recommended to me by a couple of friends. The food is in great portions and I love all of the sauces. I don’t typically like macaroni salad but it is delicious here. I’ve been here several times and they deserve a great review. The food is made well consistently and the lady running the front end is the best. Even my picky four year old daughter craves the food here. They have many options and so far everything has been great. We love it here. Hoping to keep it a family destination for a long time.

For just $10, the chicken katsu rice bowl is an absolute flavor-packed masterpiece that feels like a steal. Each bite begins with golden, crispy chicken cutlets—perfectly breaded and fried to a delicate crunch while keeping the meat inside tender and juicy. The katsu rests on a bed of fluffy white rice that soaks up every bit of savory sauce drizzled over it, balancing richness with comfort. But the real magic comes from the secret spicy mayo—a creamy, tangy blend with just the right kick of heat to elevate every mouthful. It’s the kind of sauce that makes you pause, savor, and wonder what the secret ingredient could be. Together, the crisp chicken, warm rice, and fiery-smooth mayo create a harmony of texture and taste that’s both indulgent and satisfying—proof that you don’t need to spend a fortune for something truly incredible.

Secret sauce is the best Asian fusion food in the local area of Upland! The Chicken Katsu is hard to beat, pork being just as good. If you like places like L&L Hawaiian BBQ, you’ll really love this place. I’ve just been here four times and it is now my favorite go-to restaurant in Upland. My wife and I marvel each time we leave how good the food is. The miso soup is fantastic. The katsu chicken is perfect every time. Even after 5 to 10 minutes of eating all the other great side orders, the katsu chicken never becomes soggy and is a tender as can be. The consistency from this chef is rock solid!!! Try the basil sauce with your veggies; its flavor on steroids with a hint of heat. I included a photo of the underside of a table. That may seem strange to some, but to me, it’s a way of determining the cleanliness of a restaurant when there is no gum under a table. Perhaps I was trying to be a smidgen artistic, as well (LoL). The macaroni salad is mayo based with tiny diced up pieces of apples, white raisins, and shredded carrots… way better than other Hawaiian, Asian barbecue places.
Oops, I almost forgot to mention. Be sure to try the garlic edamame! This is the best thing I’ve had in a long time, sweet and savory.

The food was really delicious and a great deal for the price! The people at the store also gave us a few samples to try which was super sweet of them. Amazing meat to rice ratio and the portions were very filling. I would definitely recommend the Japanese curry if you go.

The ladies up front are very sweet! I enjoy the food here a lot. It’s good for work lunch: Affordable, good, and filling. I tend to have trouble to look for food that isn’t super costly for my break, so this is perfect!
I recommend it!
