My humble opinion backed by yrs of experimentation and research

:
Joseph Sin el Fil - for the best Shawarma
Istira7at al Salam Qasqas - for the best fruit and juice cocktail ever!!!
Al 3irzal Faraya - for real traditional village-style lebanese food
Fakhr el Dine Broumana - is still my favorite for Mezza, pricey, but still the best quality and freshest ingredients on the table.
