There's something about using aquariums as a design element that people find aesthetically pleasing; trapping fish behind glass makes people think "luxury." I realized this as I looked at a design proposal for a Chicago restaurant called "Barrier Reef, a new wave in dining," which features 280 feet of aquariums and a three-story shark tower.
I want to see steakhouse- and fried-chicken-joint-variants, where you dine amidst cows ambling up Guggenheim-like ramps and chickens wriggling through Habitrails.
