Everytime I travel to Mannheim for business, I have dinner at Osaka. They have the most delicious sushi and teppanyaki dishes. They offer single meals but also menus. Menu ranges from 35-100 euros, divided in seperate courses; up to 10 for the largest menu. I always eat the beef rolls with mushrooms and garlic, mmmmm. If you just order one course, you also get a starter of 3 vegetables. After the dinner you're offered a candy of choice.
If you're into sushi, teppanyaki, this is the place to go! Not for romantic dinners however, the atmoshpere is quite crowded busy, and the noise can be loud from time to time. When you're assigned to your table you could wear a kimono if you want.
