I'll be in Waukesha for work the first 2 weeks in April. Is there a good place to play some EDH on any Monday-Thursday weeknight?

Mox Mania has EDH games on wednesdays.

Perfect, thanks!

Edit: Wait, is this place in Madison? Or do they have another location somewhere?

Oops, my bad. I was mixing up Waunakee with Waukesha.

Dont go to Mox Mania those dudes are crazy (we love you Mox in all truth). But seriously though Netherworld Games in Madison has modern on Tuesdays, standard on Mondays and draft on Fridays.

Games Universe in Brookfield is pretty close, I've been there a few times and its a pretty solid store. The Franklin store is my favorite place in the Milwaukee area though.
