The restaurants I think are great value for money always seem to disappear quickly

It's like, "This much for this price?"
Even considering the delivery fee, I sometimes wonder if the price is even right, but they always end up disappearing. Every time I find a new place with great value, it vanishes again.
I suppose it's hard to make a profit no matter how much they sell.
It was a Kimchi-jjigae place, and a Kimchi-jjigae with a drink, a bowl of rice, seaweed, and pork was only 10,900 KRW.
Every time I ordered, I thought it was such a good deal because they included a lot of pork.
Then, at some point, it just disappeared. I passed by and saw it had changed into a different restaurant.
The value was truly excellent—to the point where I wondered if they could even stay in business at that price.
I think they couldn't hold out because of the cost of ingredients.
