The first time I visited Madison was for a job interview and my employer put me up in the Edgewater. Unfortunately, I can't recall my room having a lake view, but the accommodations were pleasant and front staff helpful.
After getting picked up at MSN in the Edgewater limo (how pimp is that?), I ducked into the bar for some late eats and to see what was going on. Strangely enough, there were a gaggle of dentists in semi-formal wear celebrating the end of a dentist convention. I didn't stick around too long. Food and drinks--good. Hotel--good. 4 stars.
