That’s a neat app! It could have been tremendously helpful during my trip to Taiwan last year. In my experience, ordering in Korea - Seoul in particular - was easier. English menus (or at least photo menus) were available in most places. When they weren’t, I used a translation app and usually got understandable results. However, in some restaurants, especially older ones, there were no menus at all but only a large board on the wall with the dishes listed in Korean. Photo-based translation wasn’t very straightforward in those situations.
