My family likes to go to Byblos for big family dinners or events. We most recently went in November with approximately 20 people, and they always seem to be able to accommodate us. We do make a reservation ahead of time. They start you off with hummus, tabbouleh and Syrian bread. Some meals come with a salad to start. This most recent time I went, I got the grapes leaves that comes with about 12 grape leaves served over a giant plate of rice. Their rice has I believe spinach and onion in it, so delicious. The grape leaves had rice, ground beef and seasoning- phenomenal. They do also have a vegetarian grape leaves meal. Previously I have had the chicken kabobs which are also delicious.
Take note, this is certainly not a place you should go if you're pressed for time. The wait staff is attentive but with all of the courses they have and all of the people we are usually with, it can take a few hours to complete our meal.
