A sushi restaurant is an establishment that specializes in serving sushi, a traditional Japanese dish made with vinegared rice and various ingredients, including raw fish, vegetables, and seaweed. These restaurants often offer a variety of sushi types, such as nigiri, maki, and sashimi, catering to different tastes and preferences. In addition to sushi, many sushi restaurants provide a range of other Japanese dishes, such as tempura, ramen, and edamame. Customers can enjoy their meals at the restaurant or opt for takeout and delivery services. Some sushi restaurants also feature a sushi bar, where chefs prepare sushi in front of diners.
