Oregon has some great ones, right? I ran into the same wall looking for their take on beef ribs...

The Georgia Aquarium's whale shark tank gave me the same vibe. I spent whole afternoons there, but later heard about the stress from constant filtration noise. Kinda like what @davis.leo said, picturing the fish pissed off by all the pumps. Still, teaching kids about ocean life is huge, so it's a real gray area.
