Free iced tea: Vietnam's most pleasant cultural shock

You sit down at the café. You haven't ordered anything yet. A glass of iced tea appears on the table.

The first reaction of foreign customers is usually panic: "I didn't order this. How much? Is this a scam?

It's not a trick. It's free. If you finish it, they'll refill it, also for free. At most casual eateries across Vietnam, this is just the default.

What is iced tea (trà đá): very lightly brewed green tea, cooled down and filled with ice. It tastes almost not bitter and has no strong flavor. The purpose is not to be savored — it's to cool you down and cleanse your palate between bites of food, especially with oily or spicy dishes.

When do they charge: coffee shops, beer bars, and some establishments in tourist areas do charge — usually 2–5 thousand, and they will tell you beforehand or write it on the menu. If no one mentions anything, it's almost certainly free.

A few other things are also free that customers often miss:

• Fresh herbs served with vermicelli noodles, mì Quảng, or bánh xèo — if you run out, just ask for more • A small bowl of soup that comes with broken rice or chicken rice • Bean sprouts and lime with chili on the table • Cold towels at some restaurants — note that these are charged, around 2,000–3,000 đồng, so don't unwrap them if you're not going to use them

Here's something worth mentioning about culture: free iced tea exists because the weather is scorching hot and because people assume that anyone who walks into their shop should have something cold to drink. It's not a marketing strategy. It's simply basic courtesy, maintained throughout countless generations in a country where it reaches 35 degrees.
