So not to get bored, as we say in Vietnamese: "Get bored with rice, change to beef noodles" (be careful as "rice" and "beef noodles" here have been humanized...to "wives" and "mistresses"), I would love to suggest you to go further, beyond Vietnamese borders...to Cambodia, our neighboring country for some exotic foods that I saw on my way to Siem Reap in my first trip to the Word's Heritage: Angkor Wat!
On my way to the World's Heritage - The Ankor temples!
I've been to Phnom-Penh several times in the past, but only for business, sometime I did within-a-day trip to Phnom-Penh but never to Siem Reap, so my last-week trip to Angkor was my first time!
Phnom-Penh changed a lot! It's no longer the same city that I visited 6-7 years ago. Much more vibrant, much more fun! And much more things to offer to tourists, esp. those exotic street snacks vendors that I met everywhere on my way to Siem Reap!
Surprised by a numbers of street vendors selling most exotic snacks: insects!
