O'Reilly's Tripe and Drisheen ★ 4.4
The only producer of tripe and drisheen left in Ireland, an English Market stall since the early 1900s; drisheen is Cork's peppery, crumbly blood pudding.
Why locals love it: The product (tripe and drisheen) is so distinctively Cork that most non-Cork visitors walk past assuming it is not for them.
