I lied. The flatbread is more oval in shape and the filling is inside the entire bread. They serve it to you folded over in half in a paper bag, hence my confusing it with a filled semicircle. On a future visit I might take a picture.
Today I had the salted yolk & pork floss, the black pepper beef, and the dried vegetables (elsewhere called pickled veg, but dried seemed a better description on dissection) with pork. They volunteered that they have a 4-for-3 deal, so I got a barbecued chicken as well. The egg yolk one skewed more in that direction than pork, but floss is so ethereal anyway. The beef did have a pleasant peppery kick, and also had flecks of dried red pepper skins. The pickled veg one was faintly sweet. They were all good in their own ways, and I’ll bet I’m eating better on Amtrak than anybody else on the train right now.
