Shame the menu is so small,
Back in Japan my favorite burger was the Spicy Mos Cheese Burger (bun, mustard, burger, cheese, mayonnaise, jalapeno, onion, mos meat sauce, tomato, bun) I'd get it with a small serve of chips and a melon soda
my friend and I also tried: Teriyaki Burger, Teriyaki Chicken Burger, Regular Mos Burger, Roast Katsu Burger, their special Salty Butter Chicken Burger thing (limited time item) Mos Fried Chicken, Chili Dog, and probably 1 or 2 others I’m forgetting

And none of them looked sloppy and greasy like those ones

At least the price is still good enough
