Old Dong Bento
Located in the lobby of Taipei Station on the first floor, the nostalgic bento at Old Dong's looks quite nostalgic. Let's buy one and try it, after all, I'm feeling a bit hungry after the train ride. Overall, Old Dong's bento tastes decent, with the rice being cooked just right and the braised chicken leg paired with vegetables, the combination of meat and vegetables is quite reasonable. When getting off at Taipei Station, you can try buying it, it is much better than the fast food in mainland China, and it's also quite affordable at around 20 RMB.
Taiwan Railway bento can be mostly purchased on the high-speed rail or in Taiwan Railway. Their taste is slightly inferior to that of Laodong's, but they are still a good choice as food for travel.
