Start with the coffee, tis is how I do Vietnamese iced coffee, friends in Louisiana taught me about this: 1. Make some good strong coffee 2. Fill a glass 2/3 with cracked ice 3. Pour sweetened condensed cream on top 4. Pour hot strong coffee on top 5. Serve with spoon I was taught a slightly different way, but this is my take. The food truck. Turning the RV into the food truck. Need to talk to health department make sure I got everything going in the right direction. Apply for a business registration, register with irs, already have food certification, get all the rv papers, licenses, insurance, and do all the renovation!
