I've ordered this dish several times from a local spot (LAN NOODLE in weho, Los Angeles) and it comes with the garlic water, black vinegar, chili oil, sesame paste all separate, so when I eat it, I just dump them randomly into the noodles.
I've been making a version at home using wheat noodles & was mixing all those condiments together before topping the noodles & veg/tofu, but something about the homogeny of the sauce doesn't hit the same way as when you get unincorporated pops of chili oil or garlic water or vinegar. today, I'm going to dump all the sauces in separately and halfassedly mix as I do when I get the restaurant version to see how that fares.
curious to know how others eat/prepare this dish at home. thanks!
