JamieMark, Welcome Aboard Cruise-Chat!
On another thread our good Doc said no ice. I have never had a frozen drink at Chankanaab. I have had a Dos X and a chicken enchilada without any problems. That was Pre-Wilma though. So I am going to play it on the safe side for awhile.
Now, I often get some great food at Pancho's and a frozen drink at Fat Tuesday's. I have been told they have filtration systems, and no problems so far for me.
I just avoid the smaller operations, especially outside of the town limits. Why take the chance?
Again, Welcome Aboard!
