Apparently the public isn't as hungry for death row dining as some might expect. A restaurant offering the last meal experience was shut down before it even opened, according to the article here.
We suppose that means the only way to sample a true last meal is the old-school method, although we wouldn't advise anyone to commit a capital crime purely for the purpose of sampling prison fare. Instead, just whip up a few of the jailhouse recipes in our book! It's quicker, safer, and saves taxpayers millions of dollars in legal fees.
