Victory Bread has a satellite down the street from me (across from Gumri), but I haven’t hit it up yet. When I do it will be for lahmacun rather than lavash, although I love lavash.
@DogbiteWilliams goes to Victory Bread’s flagship regularly I believe. Perhaps he could weigh in on this.
There was a wonderful Armenian artisan bakery near the Olive Garden Market where I got some great lavash, but it closed a couple of years ago.
