Are you looking for har gow (as your picture shows), or steamed dumplings?
If the former, it’s hard to beat the ones at Sea Harbour or Elite. But har gow is a dim sum specialty, so look in that space for chive-centric har gow dishes.
If the latter, then try Din Tai Fung. No, I am most definitely not talking about XLB. Rather, DTF does steamed dumplings rather well, and their execution of steamed dumplings with chives and pork, or just chives and other vegetarian fillings, are rather exemplar. In fact, the DTF version of kimchi pork steamed dumplings is sort of, how do you say, pretty good?
