to say it was an adventure would be an understatement. a visa is required for this tour at your expense. the waste compartment keeps used blades in one place. if you touch it, your fingers can pick up the infection. in the mean time (having cut out the hard part) chop the oysters fine, with some hard-boiled yolk of egg. rated 5 out of 5 by kiki from they work! we nosed around a little, took some pictures, tried some rum punch, and then got back on the bus to go to the last stop on the tour.
