Why is there no restroom for the customers? The limitation of a restroom makes it difficult for a parent with more than one child or an elderly person. Please advise. Thank you in advance.

I believe it's because trying to add another plumbing system for the end of the peer would be too expensive and dangerous; another reason may be that it could violate the historical aspect of it being the first Ruby's Diner, similar to how historical houses can't be remodeled.

There is a restroom at the begining of the pier use it before you go to the restaurant
