FWIW: if you want an option for commercially prepared larb not too far from Dok Bua, I quite like the offering from S+I in Allston Village. There used to be more options than were on their menu, which might or might not be fixed; they are quite small and have a chaotic web footprint with different stuff at different prices from different ordering platforms. I like their duck larb a lot, probably not coincidentally it is *not* a lower-fat meat.
