Tohoku is a great place for fresh food, whether from the fields, mountains, forests, or seas. Restaurants range from local sake shacks to upscale sushi bars and steak houses, and dress may be street-casual to office attire. Rarely will it be formal. Menus may not always be in English, but you can often find window displays full of plastic representations of the menu. Credit cards are fine in cities, but they are not always accepted in the countryside, so bring along enough cash. In many restaurants you'll take your shoes off at the entry and place them in a cubicle.
