Street food in Vietnam is famous for being cheap and delicious, but have you noticed that prices at popular stalls in Hanoi's Old Quarter have crept up to nearly restaurant levels? A bowl of pho that cost 30,000 VND two years ago now runs 50,000 VND or more at tourist spots, while locals still pay half that in quieter neighborhoods. Is the premium justified by higher rent and quality, or are vendors simply cashing in on the Instagram crowd? I'm torn because I love the convenience, yet I worry that the authenticity of street food gets diluted when it becomes a photo prop rather than daily sustenance. What's your take on the balance between preserving tradition and making a living in a market that's increasingly globalized?
