The dark table concept was cool, but I agree that the food wasn't worth it. I'd also say that it was surprisingly loud. Without the ability to focus your hearing to where you're looking and read lips, your conversations are basically weirdly just ambient noise and most people talk louder to try and get their other table guests to focus on them based purely on volume. I think this could work if the food was more unique and there were either guest chefs that participate or if you went full SAIT culinary students final examp for this or something. It was basically food from Earls without being able to see it IMO.
What are your thoughts on hot pot? This one is more like, "LOL, what did you eat? I don't think that's how you are supposed to eat that, cook it more! LMAO." type of deal.
You should also take a look at some Japanese restaurants that focus on stuff other than seafood/sushi. I think some Korean restaurants are like this. Same as above, it's sometimes more like, "What did they serve me? Dang, that was better than expected." vs entertaining you.
Kinjo used to have the owner run around threatening the men with a knife to say things to the ladies. It's still pretty decent for that and the "side items" you can get via their Tokyo Street Market theme are fun to try (ie: Marble soda, snacks etc.)
On a completely different note, IMO a funny joke version of this might be to get a catered meal package at Calaway park. Yeah the food won't be great, but you'll have plenty of time to chat while in line and who wants to have a full stomach while going on rides anyways?
