Off the usual track in Dublin you have:
Pub: Martin B. Slattery
Address: 217-219 Lower Rathmines Road
Style: Old-fashioned
Reason for choosing: The usual old fashioned charm of the classic Irish pub, in Dublin, though not thronged with tourists or TV crews.
Pub: Leonard's Corner
Address: Corner Clanbrassil Street & South Circular Road
Style: Modern-but-cosy
Reason for choosing: Somewhat upmarket locals' pub. Tends to be lively without being overcrowded. Friendly staff.
Pub: The Bleeding Horse
Address: 24 Upper Camden Street
Style: Superpub
Reason for choosing: These days, the traditional Dublin pub style is the cavernous mega-boozer. The Bleeding Horse is one of the few places to get this formula right, retaining a traditional style with lots of nooks, crannies, galleries and secluded corners. Attracts a diverse clientele.
(The usual track, for the record, is Mulligan's, The Palace, The Long Hall, The Stag's Head and The Brazen Head.)
