Ekiben stall in Osaka Station-- while we waited for shinkansen to Tokyo ... There are light box showing visual of food inside each number of ekiben. When I ordered, I just say number only. Again, there are cool fridge for cold beverage and hot cabinet for warm beverage which allow customer to pick and handle to shopkeeper with ekiben.
This time I ordered rice similar to onigiri topped with black sesame & plum. Aside are potato salad, pickle, grilled chicken, oden, together with sweet egg omelet (Tamako).
