Shinsen is a casual neighborhood Japanese restaurant with quality fish for pretty decent prices. They have a few sushi sets (the least expensive one is $29 for 10 pieces), as well as dishes like oyakodon (a chicken and rice bowl) and a spicy tuna tower. Whether you decide to come to this modern sushi space for a casual date or just to have a solo meal at the sushi bar, expect to sit near several people who are staying in the hotel next door.
