I know I've seen Golden Mountain on Argyle....somewhere. When I'm out, I look for Dragonfly, which is gluten free and I find Golden Mountain, which is not gluten free, instead, lol. I eventually found Dragonfly, though can't remember where, either. I am sure, though, that is was in the Argyle area that I found both. It was about a year ago, so that easily could have changed, but even if you don't find it, it's always fun to go through all the stores.
I seem to recall one store had primarily Thai things - but I think it closed. It was on the east side of Broadway, kitty corner from the Green Mill.
