Here's some quotes I have picked up about it.
"The Bubble Room is about desserts, desserts, desserts"
"The sight of the Bubble room upon your arrival will fill you with delight at the zany and multi-coloured design."
"For a couple, the food is not good enough, and the ambiance is probably not appropriate...unless you have a strong personal interest in kitch, antique advertising and similar whimsical memorabilia from Hollywood and Christmas past"
and the bubble restaurant says itself..
"People from all over the world visit the Bubble Room to see our collection of memorabilia. You are always welcome to wander and view our collection at your leisure"
