In my book, they're more like a 3.5, but I didn't wanna necessarily bring their overall ratings down.
tl;dr
Good selection. Nice owners. Close-enough to me. Repeat customer.
They are what I personally consider small-sized grocery market. Why does this matter? Because the real estate determines how many variants of the same items you can carry at the store. Your local, less-than 2000 sq/ft mom-n-pop stores would be "tiny," and the likes of HMart are your "large." You get some "mega" ones in big cities like Chicago, Atlanta, L.A., etc.
If you're an immigrant living in suburban areas of the States, you get to form a decently close relationship with your local Asian groceries. I remember growing up near Indianapolis when my family first immigrated, the only place we could get any Korean grocery was a tiny place 35 minutes from our house that my distant cousins owned. These used to be your only outlets, where you can get anything resembling ingredients that's required for your own cultural cuisine, and also get in touch with news of your motherland. Growing up, one of our weekly treats was to detour there after the Sunday service and rent stacks of (probably illegally) copied VHS tapes of all Korean TV shows and K-dramas for 50 cents each and watch them throughout the week. (These were pre-internet days, which means I'm fully dating myself...) Gone are the days of sneaking back to the "employees-only" area (a.k.a. the back room) where they had 20 VHS machines cranking out copies of random variety shows, tearing open a bag of chips and chill with the cousins..
Anyway, back to Galleria.
They're not as tiny as the one I grew up knowing, or the nearest one I have in Toledo. But they're also not your large/mega HMart either. Ann Arbor has decent number of both local and studying-abroad Koreans, as well as non-Asian clients, and the size of the store serves its purpose. If I feel up to it, or have other business in the area from Toledo, I make it a point to swing by and grab whatever things I'm in need for the week. I'm always hit with a dilemma of driving 25 minutes to the local one, 75 minutes to Ann Arbor, or 100 minutes to Canton. Each time is a little different depending on what I'm looking for, but Galleria generally meets the middle ground for price-to-availability ratio. I've seen up to a couple dollars differences in any given item between the tiny store to the large stores.
Again, they have an okay variety of items. More than some, less than some. But definitely plenty to get you through your day-to-day needs. Any "specialty items," however you define them, you're better off in bigger places, at least so I've found. They're usually well stocked up. I've never had an instance when I couldn't find something I was looking for, which happens quite often in the nearest one to me.
Owners are very nice folks, although you'll definitely catch them in bad days. I've seen them in their best days and some bad days. In a lot of ways, they remind me of my parents. They'll sometimes get into arguments with certain clientele, especially argumentative ones. But I'm gonna go out on a limb and boldly say that most people don't like argumentative people? Anyway, some might consider that unprofessional, but some might say that's just life. I'm just glad I don't get into as many of these situations myself, even though I consider myself very argumentative... :-D
