Hi @Helper_Monkey -
Random Thoughts seems like a good thread to discuss this.
I’m with you. I think it’s helpful to non-members as well as members to have restaurants on one thread as much as possible. But @Chowseeker1999 patiently explained to me a little of what @J_L wrote - people have their own style and own way of posting and that’s the nature of a board. And some, like @Nemroz don’t like overly long threads, so…
I do think they and a couple of others (you know who you are) should have their own threads for the same restaurant for the simple reason, yes, they do have their own cool style, but also because they lead the charge. They make the effort to research new places, go early and report back promptly. That is rarely me, so I prefer to post on their threads. I consider my posts companion pieces. 
Plus some might think my reports are strong enough to stand out in a crowd.
Anyway, Chowseeker is right, everyone should do it their own way. Except people who start a new thread everytime they themselves visit the same darn restaurant! Okay, ignore me, I welcome them too. 
Obviously I have a lot to say about this topic and was hoping someone would bring it up.
Happy eating and starting your own thread-ing!
