My parents used to have events for college students catered by Cedars of Lebanon. The first time, they expected 25 people, so they ordered for 30, just to be safe. There is no reasonable adjective to describe the quantity of food that showed up, but "immense" or "ridiculous" might come close. The next time, expecting 25 people, they ordered for 15. There was still far too much food for our guests to reasonably consume, and our family ate leftover falafel for weeks.
You'll have the same experience dining in here. The family meals appear to be slightly expensive, but you are gauranteed to have leftovers from each of the 6 to 8 dishes that you'll end up with. A meal for 4 is really a meal for 8.
There are cheaper options, too. A falafel sandwich with fried potatoes and a salad is $4.50 and is an ample amount of food for lunch or dinner. You can buy wine two doors down at Kimbark Liquors and bring it in.
Oh yeah, the food is delicious and the staff is friendly.
