After getting sick more than once at "very local" restaurants worldwide, I tend to shy away from establishments that are just shacks on the side of the road where dishes are rinsed in buckets unless I speak the language and I can ask/read what is cooked thoroughly. Not speaking Vietnamese did not help of course, and translated menus were terrible (at one place some fish was translated into "such stop"). So all the high rated, mid-range places on Tripadvisor we tried (Cami, Linda), and even a quite "local" place in Duong Dong town that was not on TA was pretty disappointing, especially once one factors in the ~1 hour round trip taxi ride.

Wish I had known better places in An Thoi but nothing came up on TA and concierge desk did not make any references to there being anything there so I did not go explore much there.
