I've been going to Reliable for a loooong time, ever since I was a baby-faced freshman homesick for Korean food (being from SoCal which has one of the biggest Korean communities outside of Korea). It's the best Korean/Japanese grocery store in the area. (For those who mentioned Super 88... that's Chinese. There's a difference.)
Anyways, a lot of this review is going to be comparison with H-Mart (spoiler alert, I like Reliable better), since that's the only nearby Korean grocery option left... Lotte and Han A Rum both closed down around the time H-Mart arrived (edit: add more more to the casualty list... Mirim in Allston is now gone too). I really don't want the same to happen to Reliable, which is why I'm writing this review even though I'm not really an active Yelper.
First and most importantly, PRICES:
Despite being a national chain, H-Mart is generally more expensive than Reliable (a small local business). For example, $36 vs. $31 for the same sack of rice. $12 vs. $9 for a pack of canned tuna. Tofu is up to half a buck more at H-Mart. Sure, the difference won't break the bank but it just annoys me on principle.
Also, 10% discount (with a few exclusions obviously) at Reliable if you show student ID!
Store:
Reliable isn't brand new and shiny but it's clean. Aisles are a little cramped. There's no kpop blaring in the background, thank goodness. Not everything is labeled nicely in English which I guess non-Koreans might find intimidating, but the staff are generally quite friendly so don't be afraid to ask questions. The ahjummas do speak limited English but if they don't understand you, you (probably) have a smartphone! Just pull up a picture or even the Korean name of what you're looking for and show it to them. Or try asking one of the younger staff members.
Selection:
Unless you're cooking something extra unusual, Reliable has everything you need in terms of ingredients. They also have the bases covered for candy/snacks, frozen foods, beverages, ramen, etc. H-Mart has a wider selection (helped by larger space + national distribution network) but I've never had the need to take advantage of it.
Produce:
Probably H-Mart's is a little fresher due to higher turnover but generally I haven't noticed a big difference compared to Reliable's produce (but if I can't find a satisfactory item I just make a 2nd stop at Market Basket down the block since that place *definitely* has great turnover). I've gotten duds at both places. As with any Asian grocery, don't be dumb, inspect before buying (this also goes for expiration dates with other items).
Prepared foods:
H-Mart's prepared food is all Jinga brand, which is made in a central facility somewhere in the NYC/NJ area. On the other hand, if you walk into Reliable there's a kitchen in the back where you can often see people preparing the food right there, which I find preferable. They usually have samples out. In general I make my own banchan, but the items I've tried have been decent. Apparently they do catering as well.
Seafood:
Reliable has both regular and sushi-grade fish available. More recently they started selling little takeout trays of nigiri but I haven't tried it. There's also always a tub of live crabs chilling in front of the fish counter if you're into that.
Meat:
Have to admit H-Mart has an edge here, all the meats at Reliable are frozen (though IIRC this wasn't the case in the past). But for kbbq it's perfectly fine.
Booze:
They expanded their alcohol section relatively recently, they've always had a good variety of Korean/Japanese drinks (i.e. soju, sake, makgeolli) but now they have a sizable selection of wine as well. I believe they have tasting events every once in a while.
Location:
Even though Union Square isn't located on a T stop (well, maybe it'll be a Green Line stop in 10 years), Reliable is worth checking out. There's convenient free parking in the rear and several bus lines run through the area. Lots of good eats nearby too, I usually grab a quick meal at Machu Picchu chicken or Buk Kyung across the street before doing my grocery run.
