My relatives who live in Beirut do not seem too concerned! they think it should calm down soon, but really you never know. So, the only advice I can give you is to weigh your options. If it seems like it is escalating (fingers crossed for NO), then it might be wise to either not go or to limit where you go.
Now on to the food, where to begin....
North of course, my birthplace and it seems like it is yours as well. Other than falafel and Hallab in Tripoli, you have to go to the Mina (port) of Tripoli area and eat at "Abu Fadi". Absolutly the best Samke Harra (spicy fish) sandwich and it weighs about a Kilo

. Another must try is the octupus sandwich at the same place, wonderfull. There are several places that serve similar items but "Abu Fadi" is widely recognized as the best. Also in the Mina area, pick up some refreshing hand cranked lemon ice from one of the several street vendors. It is a great finish to a large spicy fish sandwich.
Shawarma in Beirut! My favorites are in the Dora area, more specifically a place called "Jabbour". I love both their beef and chicken versions and eat them at least every other day when I'm there. Also they make a mean "Baid Ghanam" sandwich aka lamb testicles. If you are lucky enough to have Kahlid as the shawarma guy that day, try chatting with him. The guy can talk non-stop, is very friendly and hooks up his buddies

. Right next door to the shawarma place is the juice joint, get yourself a nice rich calorie ladden fruit smoothie, known as a cocktail (it has no liquor though). Don't get the one with the fruit chuncks in it, get the pureed one.
If you are still in Beirut, especially in the Armenian sections, grab a Basterma sandwich or a spicy sausage sandwich. Both are equally good and pungent. the place to have those is in the Burj Hammoud area and I cannot believe I forgot the name of the exact shop even though I was there last May

. Anyhow, if you do make it to the Shawarma place above, ask any local and they will point you to what I'm talking about.
ok, that's all for now. more to come...
