The premises — located on a precipice just north of the George Washington Bridge — is large enough to accommodate walk-in revelers, and the beer list begins with several self-produced brews that bear the pub’s name. Guinness is provided, of course, both in bottles and on tap.

This no-nonsense Irish bar is heralded by a famous neon harp on the outside. Dating to the 1920s, its interior is all worn woods and Naugahydes, the walls decorated with American flags and little else. Refreshing in its straightforward, century-old simplicity, this is a great place for a beer and a shot far removed from the self-congratulatory atmosphere of most bars.

East End is a semi-elegant gastropub that doubles as a sports bar — with the kind of expansive menu — but still heavy on the bar food — that such a label implies. Come St. Patrick’s Day, you may actually be able to get in and knock back a Guinness, due to this not being a historic Irish neighborhood.

Open since St. Patrick’s Day in 1967, it’s the bar’s anniversary in addition to a spring occasion to drink. Stop here for corned beef and cabbage at the bar or grab a seat in one of the restaurant’s cushy banquettes.

Donovan’s is located at the crossroads where Woodside and Roosevelt avenues form a wee square. The area used to be paved with pubs that formed the center of an Irish community — now few remain. Donovan’s (founded 1966) sprawls out, declaring, “Proper Guinness, beer, wine, spirits, award winning food, great people.”

What’s a shebeen anyway? It’s not just a bar but an unlicensed bar with a shady reputation in the Emerald Isle. Here, Molly’s Shebeen was founded in 1960 as a facsimile Irish pub with sawdust on the floor and a flickering fireplace. Irish beers and ales on draft, plus a collection of small-brewery domestic products. Food runs from traditional shepherd’s pie to fish and chips and Irish-style chicken curry.

No this isn’t named after a bawdy house in Ireland’s most picturesque city, but after a type of small fishing boat. This West Village pub lacks gastropub pretentions, and thus is a great place to hang out and nurse a pint of Guinness, which has often been referred to as a “meal in a glass.” No untidy sawdust on the floor, though.

McSorley’s is the mother of all Irish bars, founded in 1854 and showing every year of its age, with its sawdusted floor and antique fixtures. Only two beverages are sold, self-branded light and dark ales, and watching the barkeep carry 20 or so mugs at once is part of the fun. Don’t be deterred by long lines that form at various times during the holiday — sometimes you can walk right in and have an ale or three.
