Those aren't the best examples. Wagyu sandwiches do typically get into the $30-40 range, same with lobster rolls. You should suspect ones that don't since they are probably fake and bad. Banh mi is supposed to be $4 for the same reason, since the $10-15 ones typically taste worse with a bunch of extra crap.
Complaining about a birria burrito for $22 is different though. Birria is a super premium food that should be expensive, but burritos and Mexican food in general are seen as cheap crap food in the US. So that one is more about racism than actual value judgment.
