...Is that.... mashed potatoes and a carrot in a bowl of brown gravy?
And... is that green corn?
Never heard of this served with a burger before...
That's not a green corn, but rather simple salad of cucumber, corn and carrot. Since they're in western-ish establishment, I don't think that's oden, either. For mashed potato, it looks awfully solid, so maybe it's just a whole boiled potato.
