I love eating subject stuff which is available in Chinese supermarket here.  Its taste may be similar to some of Vietnamese or Thai cuisine: the mixture of hot spicy and sour flavor.  (But be careful, its spicy ingredient is way too HOT.)

You know, my wife laughed at me when I told her if I were thirty years younger now, I might have gone to Guangxi to see if I have the chance to do the business of importing 螺螄粉 into Taiwan, Ha.
