Otaru is also known for its fresh seafood and the place to go if you want to try some of the freshest seafood you have ever tasted is the Otaru Sankaku Ichiba. The restaurants inside the market will cook scallop, mackerel, salmon and crab for you including whatever seasonal catches you buy at the market. They also have a great "kaisendon" which is rice topped with seafood of your choice, be sure to try that out for 1,000 yen.
