Make it 3D and you got a Mexican hat... and then a Higgs boson ;)

Is Mexican hat technically a double well? It's a single well I guess😅

Make it 3D by adding a revolution symmetry around the vertical axis: the double-well becomes a single valley ;)

but then you have no rotational symmetry, haven't you?

true. but symmetry for that well is not needed I guess

Not at all. It was just a funny thought to start with ;)
