PSA: It is completely normal to dislike some Vietnamese dishes. The "top 10" on most tourist pamphlets all have the same tasting notes. If you disliked the popular ones, it doesn't mean you won't enjoy the cuisine as a whole.

The Vietnamese language contains a lot of hyperboles and exaggerations and they don't translate well. People here don't eat Phở and Bánh Mì all day, but they love to praise it to the moon when a foreigner asks for recommendations. When a tourist say they hate "Phở", they either get recommended other similar noodle soups like hủ tíu and bún (which they will probably also dislike), OR they get verbally abused with insults similar to "go back to McDonalds". It's hilarious.

I have been a translator and the "de facto" tour guide for many international friends. Their favorite dishes are rarely ever the popular ones. They like the randomest things like cabbage soup (canh bắp cải), a nameless sticky rice snack on the street, kẹo dừa (coconut toffee), cơm gà xối mỡ, canh khổ qua (the fuck?) and one of my close friend was so obsessed with rau má (pennyworth) he tried to smuggle some out of the country (did not work, for obvious reasons).

When a young Vietnamese person goes out for dinner, they will think Korean BBQ, fried chicken, Chinese hotpot, Japanese ramen. You will never see a friendly get together without boxes of pizza laying around. And let's not pretend that McDonalds aren't absolutely packed at 7PM every night with Vietnamese families. Those same people will unironically go online and leave comments about how Phở is the best food in the world.

So in short, don't let fanatics shame you for not enjoying Phở. Don't mind their B.S when they spam about Bánh Mì on every post about burgers or sandwiches. Most of those people are hyperactive kids who just want to express their nationality, but immediately wince when they have to actually eat bánh mì for breakfast before school.
