It is not designed for an experience like that. The show is at most 15 minutes long and its intimate setting clashes the concept of a dinner-show. What are guests going to have time eat in a 15-minute, timed, animatronic show, besides snacks? That's why there's a snack shop placed right in front of the building. Eating a piece of pineapple or a Dole whip during a 15-minute animatronic show makes sense. Eating a full-course meal and watching a 15-minute animatronic show that wasn't designed for that purpose does not.
Let's look at some of the past dinner-shows at Disneyland, like the Tahitian Terrace, the Golden Horseshoe Revue, Billy Hill and the Hillbillies, etc. The concepts of the shows were different, but they shared similarities. They were live shows, with real actors, musicians, dancers, the performances weren't timed on a clock (like the Enchanted Tiki Room is), and their settings had some space. They weren't their own separate attractions, like the Tiki Room is, but experiences attached to a meal for entertainment with real people. Again, the Enchanted Tiki Room was not designed to be a dinner-show-type experience. Something like that screams CORPORATE to me.
Eating a full-course meal and watching something like this in the space its currently in...:
...doesn't really make sense when compared to experiences like these:
I am pretty sure that the tiki room show would just perform at random times on a loop. Not requiring you to eat a meal in 15 minutes. Think Cosmic Ray at Magic Kingdom... And you're wrong, actually.. The original idea for The Enchanted Tiki Room WAS supposed to be a dining experience.
