Really enjoyed the pork katsu with japanese curry! Service was superb! Parking was a breeze and inisde had a very chill vibe!

After a long hike, I was craving my Japanese food and went here.Rancho has some of the worst Asian food if any at ALL, but this place is a godsend. I got pork katsu with curry. Food was delicious and very filling. Probably one of the first times where I spent as much as I did and got my moneys worth. I was expecting to pay a lot more based on how old the pictures were but it's still $14 per plate. This place has good reviews for good reason. I'm coming back forever. And I don't have to drive all the way to Rowland or Torrance for decent Japanese takeout now.Please support this business. So they can Keep the prices as is.

Five star for it's value!Delicious chicken/pork katsu (with curry) bento for $14 each, you get 2 layers or katsu. That's plenty of food. You can choose the sides (e.g., rice, salad, steamed vegetables, etc.) and try additional sauces. Each tray comes with a cup of Miso soup.The restaurant is easy to locate with plenty of parking with Sprouts near by in case you need to get some groceries done. Not a fancy meal, but perfect for lunch or dinner takeout, would recommend!

This place is really about the sauces.The food at secret sauce is pretty standard but, as the name states, it's all about the sauce. And what a fantastic selection of sauces there were. We tried the peanut, the pear curry, and the spirulina. All of them were delicious, the peanut sauce was incredibly thick and the pear curry had a nice sweetness along with some heat to compliment the curry flavor. What's also great is the owner was kind enough to let us sample a bunch of other sauces and there are enough of them to warrant several returns.You're basically ordering protein, rice, and sauce. Think of it like a bento. Tried the donuts with the pandan sauce, which were ok. Overall, a nice spot for a good, quick meal.

Food: The food was so good, if it was closer to us this would be our spot. It was all very fresh and hot. So tasty and there were no weird pieces of chicken! It does come in white meat which we prefer!! They have a little water station for you to get water too! Service: The gal who took our order was one of the nicest workers I've met. She was so helpful, we let her know it was our first time and she made us feel so welcomed. Checking on us after she brought us our food. And just making sure we were good! Outside: The parking lot is huge and there is no outdoor seating. Inside: There were a decent amount of tables and they did have a public restroom. When we were eating there were a few gnats that were bothering us. But other than that it was great!

Easy to order with screen. Or order online and pick up. Small indoor seating but quiet. Love all the sauces. Everything tastes great. I like to get the fruit salad.

If you find yourself in Upland, check out this amazing hole in the wall!! Serving up fresh katsu with so many different sauce options and sides. This plate is such a good deal! You pick a protein, a sauce, two sides, and you get miso soup! This was so so good. The service was so friendly as well, I will be back!

$9 for a high quality good portion Chikeb Katsu Bowl is an amazing deal.Highly recommend.

It was my first time eating in Upland and I'm sure glad I came here because this gem of a spot was waiting for me. I was greeted instantly by one of the friendly owners and my gf + I both got Chicken Katsu sets with 2 fruit salads, house salad, and a macaroni salad. The miso soup came out quickly and was great for that chilly day. The Chicken Katsu sets came out not too long after and I was excited to see how good the food looked despite its simplicity. I had gotten the Pear Curry sauce with my set and my gf got the Tonkatsu Sauce. The owner overheard me talking about wanting to try some of the other sauces next time and was kind enough to offer samples to us! The chicken katsu to breading ratio was great and retained it's crispiness throughout the meal without being too heavy to eat. The fruit salad had a good variety and was all fresh. Macaroni salad was light and had apple bits there which resulted in it tasting more on the sweeter side which I didn't mind. I was able to try my gf's Tonkatsu sauce, Blue Lagoon sauce, Crazy Spicy sauce, and Basil sauce as well. The pear curry was sweet yet savory and paired well with the katsu. The tonkatsu sauce was as expected - tonkatsu sauce but still good. The blue lagoon (my favorite) had some acidity but was tasty when tossed onto the chicken. The Crazy Spicy and Basil sauces were good as well. I'm excited to come back next time and try the other sauces too.This place is quiet but well kept and I hope that they can stick around for as long as possible because it's one of my favorite restaurants given how good the service is, the affordability, and the generous portions of food. Come by and support this small business because they definitely deserve it!
