Mos Burger Tastes Better Than McDonald’s — So Why Is It Struggling? 5ch Asks: ‘Aren’t the Stores Always Cramped?’

From our other sites

The story

Mos Burger is sometimes said to be “tastier than McDonald’s and about the same price,” but 5ch users got into a debate over why it still isn’t pulling in more customers. The gripes raised included too few stores, long waits between ordering and getting your food, skimpy portions, and repeated price hikes. A photo showing menu prices sparked back-and-forth like “was it really that expensive?” and “which store is that even from,” with opinions split on the real price range. On the flip side, some praised the chicken items and onion rings, while others pointed out that McDonald’s own quality has been slipping lately — adding up to a verdict that wasn’t a simple case of one chain beating the other.

Why though?
2AnonymousSep 8, 2026 15:30
You can really taste the quality of the ingredients, right?
4AnonymousSep 8, 2026 15:31
I've been to Mos, but honestly I just prefer McDonald's junky flavor.
17AnonymousSep 8, 2026 15:35
Takkii needs this too — I want mobile ordering to be as easy as McDonald's has it.
19AnonymousSep 8, 2026 15:37
It's too well-behaved — doesn't give your brain enough of a kick.
21AnonymousSep 8, 2026 15:39
There really aren't many stores, huh. I'd go if there was one nearby, but I'm not driving out of my way for it.
24AnonymousSep 8, 2026 15:42
McDonald's is still cheaper
they've got set meals in the ¥500 range.
26AnonymousSep 8, 2026 15:47
If you're craving junk food, Mos just isn't quite it — it's stuck in this awkward middle ground.
28AnonymousSep 8, 2026 15:49
Nice try, hater
Mos got renamed to "Zetteria," so it doesn't even exist anymore.
29AnonymousSep 8, 2026 15:52
Mos takes way too long
the food takes forever to come out.
32AnonymousSep 8, 2026 15:53
Real American burgers look seriously good

Re: #32
That's what a real burger looks like.
What Japan calls a burger — small enough to fit in your mouth and eat by hand — that's just a sandwich.
33AnonymousSep 8, 2026 15:54
I only eat Burger King when there's a coupon for a Whopper with cheese.
34AnonymousSep 8, 2026 15:56
At McDonald's I'll grab fries and other stuff too, but at Mos I basically just get the burger.
35AnonymousSep 8, 2026 15:57
McDonald's current setup is great.
Mos Burger locations are basically always cramped, huh.
36AnonymousSep 8, 2026 15:57
It just doesn't feel like eating junk food.
37AnonymousSep 8, 2026 15:57
Not worth the price.
Though I do like the Mos Chicken.
38AnonymousSep 8, 2026 15:59
Between McDonald's and Mos, I'd pick Mos
it's just that the store is far away.
39AnonymousSep 8, 2026 16:01
Not really a fan.
Though I like their fries better than McDonald's.
40AnonymousSep 8, 2026 16:01
McDonald's has genuinely gotten bad lately
the salt seasoning is way too inconsistent.
42AnonymousSep 8, 2026 16:02
I go to McDonald's for the fries, not the burgers.

If Mos had fries like that, I'd be going to Mos instead.
44AnonymousSep 8, 2026 16:05
Aren't Mos Burger stores always cramped?
I've never seen a spacious one.
46AnonymousSep 8, 2026 16:06
The onion rings are tasty, but that portion size…
47AnonymousSep 8, 2026 16:06
The Awaji Island Burger place near me was insanely pricey but really good.
I was the only customer there, so it'll probably go under eventually.
48AnonymousSep 8, 2026 16:06
Mos's bun was kind of gummy, not great.
Might just not go well with the taco though, so I'll try a different one again.
49AnonymousSep 8, 2026 16:08
It's a little on the pricey side.

52AnonymousSep 8, 2026 16:09
Re: #49
There are cheaper items on the menu too.
62AnonymousSep 8, 2026 16:13
Re: #49
Was a Mos Burger by itself really this expensive?
117AnonymousSep 8, 2026 17:12
Re: #49
Just checked and that's the price now.
Which store is that even from?


57AnonymousSep 8, 2026 16:11
Re: #52
Around here it's pretty reasonable.

63AnonymousSep 8, 2026 16:14
It just takes way too long to come out.
67AnonymousSep 8, 2026 16:15
Re: #63
McDonald's is sloppy, honestly
the burgers are usually dried out too.
66AnonymousSep 8, 2026 16:15
Re: #62
It held out for a long time, but they've raised prices maybe twice recently.
72AnonymousSep 8, 2026 16:17
Re: #66
Show us which store that is.

Yours is the only place charging ¥700.
68AnonymousSep 8, 2026 16:16
I go McDonald's to Mos at about a 6:4 ratio.
71AnonymousSep 8, 2026 16:17
Re: #68
Don't know the total count, but sounds like it'll die out early.
91AnonymousSep 8, 2026 16:33
"Zetteria" — what's that? 🤔
108AnonymousSep 8, 2026 16:59
Re: #91
It's Lotteria after Zensho bought it out.
95AnonymousSep 8, 2026 16:38
Is Lotteria even still around? I haven't seen one in ages.
96AnonymousSep 8, 2026 16:41
Re: #95
They all turned into "Zetteria."

Background and Key Points of This Discussion

Mos Burger has built its identity around pricier, quality-focused ingredients, while McDonald’s has leaned on its huge store network and low prices — so even though both are burger chains, they occupy different lanes. What split the thread wasn’t the taste itself so much as everyday practicality: too few stores and too far to reach, slow service, and small portions. Reactions to the price-list photo were mixed too, with people saying it didn’t match the prices at their own local branch, hinting that there may be real price gaps between stores. It’s also worth flagging that the claim in the thread that Lotteria got “renamed” to “Zetteria” is just 5ch slang riffing on its parent company Zensho — not an actual name change — which is easy to mistake for fact. Beyond simple taste comparisons, differences in everyday convenience seem to be what really drives how often people end up choosing one chain over the other.
