[FOSDEM] Good coworking locations in Brussels?

A fellow JRuby hacker and I will be in Brussels for Thursday and Friday and looking to get some work done while we're there. Could somebody, on or off-list, recommend some coworking spaces or other good hacking spaces for us to visit? I've had limited lyck in the past finding coffee shops with good wifi and power, so this time I figured I'd ask ahead :) Cheers, -R. Tyler Croy
