The boys are having a fun day with grandpa and sleeping over, so my Mr. and I decided we should do something fun. Go to a movie? Nah... Go out to dinner? Hmmm... How about go to Ikea? We can walk around without kids and look at everything, and then eat dinner there.
That's what we did, it was great. Even the food was good (certainly not zaggat rated or anything, but good).
