la Mujeres is a half hour ferry ride from Cancun and is ten times as far from Cancun in chaos and attitude . Some of the best eating I've happened upon anywhere. Not one bad meal and many great meals over two plus weeks. Been the same every time I've returned
The closest things to a US chain is a small 7-11
What Isla Mujeres does have is fish as fresh as it gets, hauled in daily
by the local fishing fleet. Great Mexican cooking too.
Yucatan style. Not super hot unless you add your own picante, but full of flavor
and always fresh, to order.
Basic transportation is golf cart or scooter. There are some cars, mostly taxis, and a few pick ups and larger trucks. Plenty of bicyles and walkers too. But no traffic.
