cowboyneal:I usually eat at Especias twice on any given trip to Cozumel (just to visit with Adrian and kibbitz over there), and in no other restaurant more than once for lunch or dinner...this is not counting the breakfast at Casa Mex (which I do every day before morning dives...but not omelettes or anything like that)...I like Z's S at El Morro too...La Cocay has also become a favorite.
I have not eaten at Especias for a number of years. Will have to make sure we make it on our round in July. Breakfast at the Museum is a must as well for breakfast. We never miss it. Cocos is a must for us once for breakfast. If you have not tried La Morena, Avenida 10 between Calle 3 and Calle 5 you should give it a try. Man, I am making myself hungry.
