What train route I am taking?

A. JR Joban Line

B. Tokyo Metro Chiyoda Line

C. Odakyu Tama Line

D. All of above

I admit that my photo taking skill is pretty horrible, but the sign at the floor look like from Tokyo Metro… So is the answer is B?

Turn out it is a through train service, so is the answer is D. (-2/10 question)

As always, I will never visit Toyosu shijo because it is an obvious tourist trap. So I find one random good rating shop at Tabelog and finish my dinner.
