Don't know about being suitable for children..it's a bar that serves food. It has a wonderful view, but it is high up on a cliff.......they serve great pina coladas and have a collection of t-shirts. If my memory is correct don't use the bathroom - it's not very clean If you have kids take them to Mr. Sanchos or some other beach club.
We went to Coconuts last week. I would think it would be very suitable for children. More of a bar like atmosphere. Plus it sits on the highes point on the island and it is a stright drop off with nothing but a rope around it. It is a gorgeous view. The food I though was a little pricy. My husband got 6 grilled shrimp with about that many french fries an order of guacomole and I got an order of shrimp quesadias. He had a coke and I had a margarita and it was $40. The margrita was kind of watery. The quesadilla was a toritlla, a few shrimp and a touch of cheese and that's all. We had a private guide and saw most of the island so if you have any other questions please feel free to e-mail me. That is the backside of the island and not a lot over there other than a beautiful uncrowded beach.
Sorry guess it's just me......."more of a bar-like atmosphere with drop off on a cliff with only a rope" guess I don't see that as kid-friendly. Maybe older kids or teenagers - not youngsters. We spent a month in Cozumel a couple of years ago and went there many times- can't say there were any children there when we were there.
Thanks everyone for your input. Actually, kids enjoy bar atmospheres--I think it's exciting for them. And, since bars are usually noisier, it doesn't make their parents nervous as do very quiet, fancier, more sedate atmospheres. Some true bars don't allow children, though. But, at lunchtime, that shouldn't be the case.
