If it was another restaurant or mani/pedi coupon I wouldn't post, but I think this is a good groupon, much like the discounted membership Groupon offerred to the Chicago Art Institute:

Chicago FT'ers, Today's (Fri Feb 5) Groupon is a discount on an Adler Planetarium membership: http://www.groupon.com/deals/the-adl...er-planetarium
