Sundae or soondae, depending on how you spell it in English, is a Korean blood sausage filled with glass noodles, offal, and meat. It might sound like adventurous eating akin to haggis but this wildly popular traditional dish is eaten dipped or in soups and features an addictive crisp yet bouncy texture — Jinsundae is one of the most popular Korean restaurants in HCMC for a very good reason!
