Hal or Al-Hal or Halal... depending on the language, is a word somewhat similar in meaning to kosher (or kasrut).

it means the meat has been prepared according to islamic law, and is "clean". (which is what kosher means).

i eat kosher chicken from the deli, and Hal al meat from the falafal guy...

so is suspect the Al-Haloub cow just is a way of saying "Kosher Beef"-- islamic style!

how was the food.. i can't say i have specifically eaten iraqi food (i have an iranian friend and have eaten iranian, and i don't think there is much different.. what did you have.. (and no, i am not turning this into a food thread!)
