For me, there is little better than a perfect Lachmacun. I found a beautiful streetside oven in downtown Beirut. The oven man was cranking out at least a dozen lachmacun every 3 minutes. For just a dollar, you can be quite well fed.
In Beirut with a hankering for Lachmacun, check out Al Falimanki in Achrafieh! That's one of my favorite.
