Noble Fish, in Clawson, Michigan. It is just north of Royal Oak (popular bar district), or 15 miles north of Detroit.
Anyway, it is really a Japanese fish market that has a sushi counter in the back. They have probably enough seating for 15. They have won awards year after year for best sushi in the state.
Prices are great, sushi/sashimi is even better. Here's a link to their website. If you click on "Restaurant" near the top you'll see more info and a link to their menu with pricing.
