Ho Chi Mind Your Wallet.
I think as a tourist destination, HCMC needs to learn the difference between making money from the tourism sector and just plain scamming. Cyclo and taxi drivers to simple restaurant two-menu scams can break a traveler into never coming back. Whether or not it's intentional shouldn't even be up for speculation. Aside from that, HCMC is a bustling and growing city that has much to offer; the culture is brimming with promise and I expect good things to develop in the years to come.
Insider Tip:If you end up on a Cyclo, pay the agreed price and never fall for the 2nd pamphlet scam. Walk away after paying and never feel intimidated. Vietnamese can smell fear, so enter the country fearless. Ask to see the Vietnamese menu at restaurants, and if they refuse- walk out. Aforementioned applies. Be friendly because most Vietnamese are friendly and don't fall into the typical scammer stereotype. Be courteous when applicable and be open to new things.
