My first experience of Kaza Maza and its Syrian cuisine was very strong on the food end (fattet hummus!), but not so strong on the service end, but they were having a rough day and I recognized that (it happens). Recent experiences have been nothing but perfect (food and service both) and Kaza Maza quickly became one of my faves of 2010.
Start with a selection of 3 or 5 of their phenomenal cold mezze, choose a fattet hummus from among the hot mezze, and go from there. Outstanding. Friendly, too.
Live music from time to time.
