Stalls may be one of very Asian things.
In Japan, Ramen (noodles in a hot soup) stalls are the most common ones you probably find.
In Japan, many workers (especially males) have this weird tendency of eat ramen after drinking.
Ramen for a midnight snack, like when we are a little hungry after drinking.
We often call it “shime no ramen (締めのラーメン, ramen to finish up with).”
Of course, that doesn't necessarily mean that you have to have it at a stall.
but if you're in Japan why don't you?
In front of Shinjuku Station (at South gate)
Stalls are often found near station exits but they are recently restricted by strict road laws.
But if you find one, try this midnight snack to finish up your day!
