Kai Modern Japanese Kitchen is gearing up to take over a prime corner in downtown Aurora, stepping into the historic Hobbs Building next month. The modern Japanese spot will occupy the corner space at 2 N. River St., replacing Leilani Asian Fusion, which closed last July. Developers say Kai is the latest in a growing cluster of restaurants and nightlife options that are turning the revamped building, with apartments upstairs, into a busy hub rather than just a pretty facade.
Menu, timeline, and what to expect
Kai is planning a lineup that leans into Japanese comfort staples, with sushi, ramen, edamame, and other favorites on the menu. Its hibachi will be cooked in the kitchen instead of at tables, according to the Chicago Tribune. The paper reports that the restaurant is expected to open in late April and will be operated as part of JH Hospitality Group.
Where it will sit and who owns the building
The Hobbs Building stands at 2 North River Street and has been redeveloped as a mixed-use project that pairs ground-floor dining with apartments above, according to JH Real Estate. Hoodline previously chronicled the first wave of restaurant tenants and the broader food revival in a piece about Aurora’s culinary scene.
Basement plans: Copper Dome and The Hideout
Kai is not the only project in the pipeline. JH Hospitality Group also plans to open The Copper Dome, a lounge and speakeasy-style spot in the building’s basement, along with a separate gaming lounge called The Hideout, according to the Chicago Tribune. The Tribune reports that The Copper Dome is expected to debut two or three weeks after Kai and will initially serve drinks and small plates sourced from the upstairs restaurants. The Hideout is projected for late fall 2026 and is slated to include shuffleboard, pool tables, dart boards, and a two-lane mini bowling alley.
A brief look back at Leilani
Leilani Asian Fusion opened in August 2024 as part of the Hobbs Building’s first crop of eateries, as reported by Shaw Local. Community posts and local listings later indicated the restaurant had closed in July 2025, and a fundraiser for staff followed in the weeks after the closure, according to Aurora Buzz.
What this means for downtown Aurora
Developers say Kai’s arrival is another sign that River Street is steadily turning into a bona fide dining and nightlife corridor, with new restaurants and fresh residential units reshaping the block. The trend was dubbed an “Aurora-sance” by the Daily Herald. The mixed-use approach is intended to keep foot traffic flowing day and night and to connect new residents to downtown Aurora’s cultural life as the city’s revival continues.
