I found an ad on the floor at work today that said free burgers on April 2, I think from 5 to 7. Can't find the ad now, and they don't appear to have a website, so any other details can probably be found in the restaurants.
The city paper had an ad for this on the cover of their issue last week. It says that it is all day and that no coupon is needed. At the bottom it says "code word: yowza".
