Time Out says
An all-night Irish pub for friends and strangers.
The Shannon is an Irish pub in Montparnasse where you can, should you wish, guzzle draft beer and headbang to AC/DC until 5 in the morning every night of the week.
The décor is sombre with Spartan furnishings (stools, benches and barrels). On the face of it, the bar is fairly unremarkable: the staff is friendly enough, while the pints are on the expensive side (between €6.50 and €7.50). But the bar’s décor and offerings are not the real draw. We come for the inclusive atmosphere created by its open and approachable clientele. Free of the usual Parisian tics, clients come to the Shannon for nights out with friends, pinball tourneys and – shock of all shocks – to meet new people. Fáilte!
