Dive Bar. I've been in here several times and the environment changes constantly. On the weekend, at night, it's a popular "young person" hangout with loud music and a DJ. During the week I've seen Irish folk groups singing. Note, there is NO food unless you want old chips or slim jims.
Review Source:If you're looking for the quintessential no-nonsense dive bar, this is it. This is one of those places that I don't frequent enough, yet every time I step foot inside, I won't leave until closing time. The bartenders are always one step ahead of you and are never anything but awesome, especially Judy, a total sweetheart. They properly do what bartenders should do: dole out ice cold (and CHEAP) PBR drafts and generous shots of whatever your heart desires. Popcorn machine is a bonus, nice TV's with a constant stream of anything sports-related, and a pretty killer online jukebox make for a proper night of drunken fun.
The big draw is the entertainment on the weekends. There's never a cover, and the guy checking IDs at the door is actually a nice dude (unlike that fat piece of garbage and his leather daddy cop buddy over at the Beachcomber). And I cannot stress this enough, if you happen upon the right night when The Coalition is playing here, open up a tab and get comfortable, because they are arguably the best cover band you'll ever experience. They take your traditional classic rock cover sets and throw you habitual curveballs with stuff by the likes of Curtis Mayfield, The Roots, and even Amy Winehouse, nailing every one in the process. And luckily, Malachy's has a sufficient dance floor to efficiently cut a rug.
I digress, this is a bar review after all. Just give this bar a shot, especially if you want to have a good time in Quincy Center with none of the douchebaggery of the typical "Quincy Center bar". I doubt you'll be disappointed.
This is definitely an interesting little place.
A couple friends and I stopped in last night as an "after party" of sorts after getting back from a wedding we had just attended. Drinks seemed decently priced - I think it was around $2.25 for a draft of Bud Lite, but I was the DD sooo all I had was water - AND, as others have mentioned, they have a popcorn machine. We ate around 6 bowls altogether before calling it a night (hey, we were hungry!).
Though it seems like it might be a place for regulars, we were accepted without question, and even had some conversations with the old guys.
They get one star for having a dart team and one star for being next door to Nick's Pizza & Little Duck. I've been to some shitty bars, but this is easily the filthiest place in all Quincy...and that's saying something.
If you do end up here please just order a beer and sit at a table and do nothing else! That means dont use the bathroom, dont look at a  patron the wrong way, try not to breathe too much and dont eat the popcorn!
This is the ultimate Quincy neighborhood bar. Â The crowd ranges from the freshly 21 to the retired Irish man sipping on his pint while reading the newspaper. Â The service is friendly and it is home to all that enter. Â The Jukebox forever sings the clash with the occasional hiccup of a few 80s songs mixed in with some classic rock. Â This place is full or bar Olympics. Â There is a pool table, dartboards, pub game machine, Keno and a bunch of TVs. Â If you ever want to really feel the roar of a Boston crowd on a big game day this is your spot to pick. I do recommend, for your own safety, please only adorn yourself in Boston fan ware. Â The dress here is extremely casual and if you feel the need to dress up a pair of adidas warm up pants, shell toe shoes and a nice sweater will do you good. Â I do not think they serve food here but they do have a pop corn machine. YUM YUM!!! Check out this local hot spot for some flavor!
