I started out with the Edo on Park Street a number of years ago, and was happy to see they'd opened a second location. The Monona venue is rarely super-busy, and thus generally quieter than its Madison sibling.
Sushi is of decent quality for what's available in the Midwest; not the best in the area, but FAR from the worst. I'd call it solid and reasonably-priced.
Service can be somewhat mixed - it's been inattentive/slow at times, and fine at others. I wouldn't pick this place (unless you got takeout) if you were in a rush.
