I was impressed with this translation...." Crispy Hot Sandwich". It is....Tai is snapper or sea bream.
It is called so because of the shape. Traditionally, it is supposed to be sweet... This is fusion and innovation.
The inside is international... such as German Potato, Italian ( pork sausage, tomato sauce, cheese etc. ) ... I was running from A to B skipping lunch today. I could call this lunch.
What I chose was German Potato. Italian was tempting, but I was wearing white blouse, so did not want to drop tomato paste on it.
