Need help with Horace's story request!!

[SAiNT_4-sHo]

Hey all, so I have been TRYING my hardest to get the "Room to Grow" step of Horace's story done and part of it just will not pop and so I am stuck. I asked on their Twitter page about it and have gotten no response and I don't have discord on my phone and my computer has given up on me. Anyhow, I have fully upgraded the restaurant and that is marked as done. The issue I'm having is serving 5 tables that give a minimum rating of 70. I've done several services now, most with tables leaving ratings anywhere from 85-100 and it will not complete out so I feel stuck. I hate to think about having to start over yet again (got hit with the lovely save corruption before the patch) because there was something I missed, so I'm reaching out here to see if y'all can help me any. Do I need to be serving specific dishes?? Does it need to be dishes only I make?? I'm just stuck, haha. Thanks all in advance for the help!! ??
