Koi Sushi & Hibachi has replaced the former Umami name on Peachtree Parkway in Suwanee.

On Peachtree Parkway, in the everyday shopping strip between Home Depot and Target, the former Umami Sushi & Hibachi has a new name on the brick facade: Koi Sushi & Hibachi. The restaurant sits at 2631 Peachtree Parkway, Suite 540, in Suwanee, a pocket of the corridor that feels equally familiar to Johns Creek, South Forsyth and Suwanee families.

The name is a smart one. In Japanese, koi refers to carp, and the ornamental koi fish is widely associated with good fortune, perseverance and prosperity. For a restaurant refresh, that gives the name a little symbolism without making it feel forced. It is short, memorable and looks good on a sign.

Inside, Koi still feels like a pleasant suburban sushi-and-hibachi spot rather than a theatrical hibachi room. There are high ceilings, warm wood trim, a decorative ceiling panel, an open sushi counter and tables spaced well enough for families. The music leaned modern rather than traditional, and the service reflected the international mix that defines this area as much as any menu does. But the food itself stayed close to what people come for: sushi, rice, vegetables, grilled chicken and the kind of easy Japanese-American comfort food that works on a weeknight.

One of the strongest plates was the hibachi chicken, served with a neat mound of white rice, sautéed vegetables and browned chunks of chicken in a glossy sauce. The chicken was tender, juicy and glazed in a mildly sweet sauce that made it easy to keep reaching for another bite, while the vegetables — broccoli, cabbage and carrot — kept the plate from becoming too heavy.

The fried rice was generous, closer to a full meal than a side, with chicken, broccoli and cabbage folded through the rice. It had the familiar soy-sauce depth people expect from hibachi rice without turning into a greasy pile.

The salmon avocado roll was the cleanest dish on the table: a long white platter with neatly cut pieces, a modest filling of salmon and avocado, plus the standard companions of ginger and wasabi. It was the kind of roll that tells you whether a place is handling the basics carefully. In this case, it did.

No international restaurant in North Atlanta exists in a museum case, and Koi is no exception. The menu is tuned for local taste buds, as most suburban Japanese, Korean, Thai, Indian, Mexican and Mediterranean restaurants here tend to be. But that does not make it less useful or less enjoyable. It makes it part of the way this corridor actually eats.

The next thing to watch is ramen. The restaurant is preparing a new menu tied to the Koi name, with several kinds of ramen expected to join the lineup. A reliable bowl of Japanese soup would give Koi a colder-weather hook and a reason for regulars to come back beyond sushi rolls and hibachi plates.

Price-wise, Koi sits about where many casual North Atlanta sit-down meals now land. A main plate can come out around $20 after tax and tip, depending on what you order and how you split the table. That puts it in the practical dinner range rather than the special-occasion category, especially for families who want something nicer than fast food without committing to a long, expensive meal.

The same small plaza is also becoming more interesting for international dining. Turkuaz Mediterranean Grill & Pizza is next door at 2631 Peachtree Parkway, Suite 530, serving Turkish and Mediterranean dishes such as kebabs, pide, lahmacun, hummus and baba ganoush. The restaurant opened in Suwanee in 2025 and adds another reason to notice a strip that might otherwise look like just another Target-and-Home Depot corridor.

For Koi, the rebrand may turn out to be more than a new sign. If the ramen lands well, the former Umami could become one of those easy suburban keep-in-mind places: sushi when one person wants something light, hibachi chicken when someone wants dinner with rice, ramen when the weather turns, and enough comfort in the room that kids and adults can both settle in.
