There are many Vietnamese foods that are easy on the Western palate - gà chiến, phởand gỏi cuốn, to name a few, but there are plenty - hột vịt lộn, chân gàand quả sầu riêng - that are a bit tougher to swallow. Some Asian Americans have made a brilliant video, ‘Asians Eat Weird Things’ that celebrate some of the foods Westerners find a bit bizarre.
We actually think most of these are ngon quá.
