Yes! There are better options available if I want to sit down for a meal, or even just wait for a couple of minutes for someone to fry me a piece of chicken to order.
That's _not the point_! Both the SEJ meals, and FamiChiki, are _fantastic_ for what they are — available in literally tens of thousands of locations across the country, and available _instantly_, 24/7.
They're both _not that special_ if you compare them to a "real" restaurant (though, and I will die on this hill, FamiChiki is hands-down better than a good ~80% of chicken I would get in a restaurant in my home country; but that's a somewhat different conversation).
But if you compare them with convenience store meals available elsewhere in the world (especially in the broadly understood West), they still _are_ pretty damn special.
(And don't get me started on the 7-11 frozen pizzas from Da Isa. Those, reheated in a Balmuda also clear a good 75% of "real" pizzerias back home, and not because pizzerias in Berlin or Warsaw are particularly bad!)
