I do them and honestly they are a pain in the butt. You evaluate 4 restaurants and they reimburse you $15. The food is mediocre at best. And, for the 1st restaurant you have to spend 20 minutes there and then space each restaurant out at least 5 minutes. This means that you spend about 2 hours doing these, not including the report. The report takes about 45 minutes to an hour.
I live near Cincinnati and I have a annual pass to the Children's Museum and honestly it's not worth it. Plus if you bring your kids with you, they get frustrated because they want to spend time in the museum, not walking around different food places.
Just my 2 cents.
