I visited Biwako Sushi with some coworkers last Friday evening, and found the experience enjoyable, if conventional. To be frank, I have a high bar for sushi, and this venue was pretty similar to the Ann Arbor standard. The venue is small and cozy, with wood furnishings. Our waitress was kind and considerate, often calling-out when she needed to reach over/behind us. I ordered a BiBimBap without the hot stone (which would have been an extra dollar for some unfathomable reason), and my total was around $13 with tip. I'd recommend using hot sauce liberally, in combination with soy and eel sauce. Overall, I enjoyed visiting this establishment, but think it's pretty average considering it's a full half-hour drive from our workplace. If you're near downtown Ann Arbor, I'd recommend checking out Miki for the convenience and quality.
This was ok sushi, I did not really enjoy the rolls I picked. They were sweeter than I thought. I will try again and get one of my typical rolls.
