Are the restaurants in Bang Na on this list bad?

Not necessarily. They are places where the Google score is at least 0.6 stars above the Wongnai score and the gap is statistically meaningful given both rating counts. Different crowds rate differently; the list shows the disagreement, not a verdict.

Wongnai is Thailand's largest local restaurant review platform, used mostly by Thai diners.
