Oppa Chicken is the dedicated Korean-fried-chicken-and-rice-bowl room from the operator family that also runs Ramen Fuji and Ichifuji. 3412 South Western Avenue, in a west-side strip-mall format, with 299 reviews at 4.5 stars. Closed Tuesdays. The menu is more focused than Ichifuji's — no ramen, no corn dogs — and the focus rewards the kitchen with cleaner execution on the things it does specialize in.
The orders. Tempura-light boneless wings, soy garlic and honey garlic glazes. These are the headline. The tempura batter is lighter than the cornstarch-heavy batter most American fried chicken uses, and the result is a wing that's crispy without being heavy. Soy garlic is the classic; honey garlic is the slightly sweeter alternative. Some menus also feature spicier glazes seasonally. Order both glazes if you're with a friend who can split.
Bibimbap is the rice-bowl headliner — Korean mixed rice with sautéed vegetables, gochujang, and a fried egg on top. Oppa's bibimbap is properly assembled, the gochujang is dosed right, and the egg yolk runs into the bowl when you stir it. It's the order for diners who want a complete meal in one bowl.
Tteokbokki is the Korean rice cake snack — chewy rice cakes in a spicy gochujang sauce. This is the thing Korean street food obsessives will recognize as the test order; if a Korean kitchen can make tteokbokki right, the rest of the menu follows. Oppa's tteokbokki is right. Order a small portion as a starter.
Korean tacos are the cross-cultural concession — Korean BBQ in a tortilla, with kimchi and other toppings. Cute, reasonable, fine. Not a must-order.
Steak udon is the noodle-bowl alternative for diners who don't want soup or chicken or rice. It's the comfort-food order. Better than you'd expect.
The portions are generous. A bibimbap plus an order of wings is a meal for two if you're not big eaters.
Hours. Closed Tuesdays. The schedule mirrors the operator family's — Ramen Fuji is closed Tuesdays, Ichifuji is closed Mondays, Oppa Chicken is closed Tuesdays. The family rotates closures so at least two of the three are open every day except Monday and Tuesday, when only one is open. Plan accordingly.
The room is similar to Ramen Fuji's and Ichifuji's — small, bright, casual, focused on the food. Counter-and-table service depending on the volume.
Parking. The strip-mall lot. Easy.
For takeout: Oppa is built for it. The wings travel perfectly within fifteen minutes of pickup; after that they start to lose crispness. The rice bowls travel well. The tteokbokki travels fine. The Korean tacos are best on premises. Call ahead twenty minutes.
Cards and cash. The phone is (605) 334-8888. No standalone website; the Facebook page is the operating presence.
Compared to Ichifuji (the sister restaurant on East 10th): same kitchen, different menu emphasis. Oppa is the wings-rice-bowl room; Ichifuji is the wings-ramen-corn-dog room. The wings are the shared menu item. If you're specifically there for wings with rice and a Korean side, Oppa. If you want wings with ramen and a corn dog, Ichifuji. Different sides of town also matters — Oppa is on the southwest, Ichifuji is on the east.
Compared to Ramen Fuji (the third sibling on South Minnesota): Ramen Fuji is dedicated ramen. Oppa is dedicated Korean comfort food. Same kitchen pedigree, different cuisines.
Compared to KPOT (the all-you-can-eat Korean BBQ chain on South Louise): completely different format. KPOT is buffet-style, $36 per person, two-hour seating. Oppa is order-and-eat, $15 per head, focused execution. KPOT is the entertainment-format Korean experience; Oppa is the food-quality Korean experience.
If you've never been: order the soy garlic wings, one bibimbap, and a small order of tteokbokki. About $25 a head. That's the introduction.
If you're a regular: rotate through the rice bowls; the kitchen does each of them well, and trying them all over a few visits gives you the full Korean comfort-food survey.
For groups: parties of six or more should call ahead. The room can flex but doesn't love large parties without notice.
The operator-family-portfolio framing applies here too. If you eat at Oppa, you'll find yourself eating at Ramen Fuji and Ichifuji within the same month. The consistency across the three is the tell — the kitchen knows what it's doing across multiple Korean and Japanese formats, and the only complaint regulars have is that the family hasn't opened a fourth concept yet.
The bottom line. Oppa Chicken is the dedicated Korean-comfort-food room in Sioux Falls, and the third leg of an operator-family portfolio that's the most consistent thing in the city's Asian food scene. 4.5 stars at 299 reviews. Closed Tuesdays. Order the wings. Stay for the bibimbap.
