Fishbone Harry's is most likely a hoax. The opening paragraph reads like an advertisement. Most people would say "your restaurant" not "Fishbone Harry's." Their name is also used in the closing paragraph of the letter. This is definitely an ad meant to get out to the community. Imagine every local newscast reading the opening paragraph / ad of the letter and mentioning their restaurant by name.

@Dangerous Spaces yup, it's your fault.

Ring the bell, time is up!!!!?
