The "Irish BLT" ($5.25) commands a modest premium compared with the classic American coffee-shop version (also available here). The difference, as you've gathered, is that fat-streaked bacon made from pork belly, the common style in the United States, is swapped out for leaner hamlike slabs made from back meat. Irish bacon makes a bulkier sandwich, with but one notable shortcoming: You can't order yours crispy.
