Unlike other reviewers I had an easy time finding Cafe Eight just by looking at a map. From the Nakamegura stop we walked up Yamata dori until we crossed over the water. Don't turn on that street, but go up one block and take a right. The restaurant is about a block and half away.
Inside the restaurant was dimly lit, but cozy for a rainy night. I opted for the prix fix meal, which included a small sampler of 3 appetizers, a large portion of soup, a weird potato casserole that I found to be inedible, and a really delicious sandwich that came with a side salad. The salad dressing was really delicious. My partner ordered the vegetable curry which was fine, but not remarkable. Came with salad and yummy pickles. Overall the food was tasty and welcomed, but a little expensive. I don't know what was up with that potato casserole though.
They do sell some prepared food items like cookies. I picked up a pack of 3 sakura biscotti and was shocked that they were 700 yen each!
