birria food trucks
Does it have to be a truck? Do you care if it's lamb or do you only want goat? If you aren't stuck on a truck and don't mind lamb (it may be a lamb/beef mix) then try Mexikosher http://www.mexikosher.com/ on Pico near Robertson
There is a food truck called Aires Oaxaqueños that parks out in front of Liquid Kitty on Pico (in between Bundy on the W and Barrington on the E) http://thelosangelesbeat.com/2011/12/... according to this blog it is there "Monday, Thursday, Friday and Saturday every week from about 10 PM to 2:30 AM"
