OP, what region are you from? I remember sushi being really cheap in Sydney and it was considered a go-to for students. But here in the States it's more expensive and (at least in Dallas and Denver) you don't really want to go to anything less than a sit-down restaurant for it.
Yeah we ordered the "good" sushi and it came to $90. Was not worth it, but I wanted to taste the good stuff at least once. I mostly prefer the eel, salmon, and California rolls and the quality of em at a buffet I like is enough for me.
Are these dollarydoos? I mean it's cheap even if USD, damn, here we can really just get it delivered, and then it's like 20/25€ per person kind of thing for run of the mill sushi. I think some of the more expensive supermarkets sometimes have small boxes but these are gross and not that much cheaper.
Still, I'll always remember checking out the sushi stand at Mexico airport and figuring out after checking my conversions that they were 7/8$ PER SUSHI! I stopped complaining about my local prices after that.
I was gonna say where in Mexico would they charge that much, but an airport is always the priciest place for the most mid of meals. But I like how big Chinese and Japanese food has gotten in Mexico last I visited. Got my fill of sushi and enough to take back to others for 15 USD and it was delicious. I always buy snacks or meal before getting to an airport, those prices are always robbery.
Yeah I've only been once and I was way too busy being extatic about tacos to think about eating anything else but local stuff while I was there. These sushi and that stand actually looked really nice, which is why I was checking it out, but yeah I'm not about to drop Michelin star restaurant kind of money for airport sushi.
There was a sushiya or something like that in my cafeteria in Texas University so I'd get a spicy tuna roll every now and then for lunch. This was a decade ago.
