Sligo Pub, open for three quarters of a century under several different names and owners, claims to hold the neighborhood’s oldest liquor license. Drink whiskey or beer, it’s all pretty affordable, and watch some sports or play Big Buck Hunter. Hurry in while you still can — Sligo is one of several businesses that may shut down to make way for a new lab building in Davis Square.

Don’t expect to actually eat lunch at Paddy’s Lunch (unless you count cold beer as lunch); do expect cheap beers and classic old Cambridge hospitality. Paddy’s has been around since 1934, cultivating generations of regulars and sponsoring countless local sports teams along the way.

Eddie C’s is a Maverick Square institution. It’s cash only — because of course it is — and the jukebox is analog (and the tunes are killer). The PBR pitchers are cheap, as is Jameson on the rocks. And those Jamesons are strong — they’ve been described as a “townie pour.”

Irish Village is in good company in Brighton, which is lousy with Irish pubs. This one dates back to 1970 and is a particularly good spot to grab a pint of Guinness, play some darts, and snack on a toastie (toasted cheese sandwich).

Biddy Early’s — the self-proclaimed “best damn dive bar in Boston” — is cheap and constantly soaked in beer. It’s also one of a precious few places in the city where townies and slickly dressed finance bros intermingle effortlessly. There’s simple comfort food available on the menu, such as chicken tenders, burgers, mozzarella sticks, and the like.

Ah, the Silhouette Lounge. What is there to say about the Sil that hasn’t been said already? Pitchers are cheap, drinks are cheap (and massive, and strong), there’s free popcorn, there’s a pool table, there are many dart boards, and there are free hot dogs for life for anyone who devotes a tattoo to the bar.

Like Sullivan’s Tap, Theatre District dive bar the Tam closed a few years back but came back to life, mostly the same, under new ownership — a group of investors going by the name Greater Boston Bar Co. has been reviving a bunch of local bars. (One or more members of that same group are separately involved in the Silhouette in Allston and the reopening of Somerville’s Thirsty Scholar, too.) The Tam is just the right combination of no-frills and cheap beer that you’d expect from a proper dive.

The food at the Corner Pub isn’t half bad for a dive bar; try one of a dozen deep-fried egg roll varieties, stuffed with fillings like mac and cheese or chicken pot pie. The draft list is also pretty great, too, especially for the drinker who likes local craft brew.

It’s cheap; the drinks are strong; one guy featured on the bar’s now-defunct website “can say with 100% certainty that this place is, by far, the worst bar in Boston”; and Esquire named it one of the best bars in America seven years ago. Note: Outside food is welcome.

Patrons can play pool and drink cheaply at Shannon Tavern, a well-worn watering hole that dates back to the 1960s.

Come early, bring cash, and hole up for hours at the Behan, a friendly neighborhood dive that occasionally hosts live Irish music sets. There’s no kitchen, but if you’re lucky, you can catch a food pop-up (burritos! oyster shucking!) every once in a while.
