A few years back, it seemed like you couldn't throw a brick in a crowded restaurant without hitting someone eating mahi mahi. These days, now that I'm allowed back into restaurants again provided I'm not carrying any bricks, not so much. But it was ubiquitous for a while.
One of the side effects of its popularity, for me at least, was that I never bought it for home cooking. If the grocery stores I shopped in carried it at all, it was more expensive than other, trustworthy, known-quantity fish. So I never really tried it or worked with it.
