Anyone you use, is going to cost you about $350. I have had several parties where we have used a Taco Guy and that is about the standard as far as price goes. I will look through my cards and see if I can get a business name. the ones I have used though normally have three kinds of meat, chips and salsa etc..
A Taco Man is the best way to go. We had one for my girls Dad's "celebration of life" party after he passed away. Fed about 25-35 people and we had leftovers. Also did one for her Bday, its the best way to. I can see if I can dig up some # if you would like, just thinking about street side Al Pastor tacos is making my mouth water
