Happy to echo the sentiments here - good, honest shop with fair prices.
No up-sell here - I've actually had them tell me I didn't need work after another shop tried to tell me I did. Keeps me coming back, for sure.
Awesome building, and historic - apparently, the city of Monona was founded there! http://www.mymonona.com/pages/parks_recreation/parks_open_space/details.php/31/parks_open_space/schluter+beach/
If you have time, grab an ice cream at the bait shop a couple of doors down, and wander over to the lake.
