After emailing my review to the owners of the Auld Dubliner, they responded very quickly and told me what action they had taken so that this doesn't happen to anyone else. (Turns out the gal with a barefoot soaking in ice resting it on a bar stool wasn't an employee after all, so there wasn't anything they could do about that.) They did, however, ask the manager and other staff on duty that day and found out exactly what happened with our order. Apparently the waitress didn't put it in correctly so it never got back to the chef. Rather than admit her mistake, she blew it off. The owner assured me he had stern conversations with all concerned and is confident it won't happen again.
I was very impressed that one of the owners took the time to contact the restaurant to get all of the details, then took the time to reply back to me so quickly. Apparently they really do take service very seriously, and my friends and I will be giving them another try after all.
