In the middle of a very long day, my girlfriend and I decided to stop in at ORIBIO for lunch before we checked out the Suita Expo commemoration park. As I entered the restaurant I was struck by the range of foods available for sale out the front, particularly a wide variety of reasonably priced TVP (which I wish I had found a year ago, they would have made my life a lot easier).
We entered the dining area, and we were the only people there. The dining area was beautiful. It only seats 18 people who sit in two lines either side of the tables. We sat on the tatami side of the dining area. Behind us was a small garden area with a water feature. All around, it was very beautiful.
The server brought us a menu and water, and a few minutes later returned with an English menu. I ordered the katsudon set: fried "pork" (tofu) on rice, with some konyaku noodles and a soup; my girlfriend ordered the tartar "fish" burger set, which came with smiley fries and a glass of juice. Both meals were absolutely delicious, though a little small, and, while not particularly expensive, certainly weren't cheap by Japanese standards.
Overall, the experience was very positive. The location was a little round-about to get to, and the meals were a little small (if you're hungry, you might want to get more than just one meal), but the food was delicious and the environment was beautiful (the best of any restaurant I've visited in Japan). I'd highly recommend this place if you're in the area, and if you're not, I'd recommend eating here as part of a day trip to Suita.
Cons: Out of the way, Smallish meals
