Hinode Japanese Restaurant, home of the all-you-can-eat sushi buffet, will close its doors on May 15th at Rockville’s Congressional Plaza. Located on the back side of the shopping center, where more than a few jokes have been made about the aquarium store next door, Hinode had been in business for 30 years. If you’re looking for another all-you-can-eat sushi spot in that area, Umi Sushi & Seafood Buffet is on its way to the former Miller’s Ale House space.
