While I appreciate ambitious aspirations, the title "Banh Mi Queen" is a bit of a stretch. At most on the nobility hierarchy, we're looking at a Banh Mi Duchess. And even then, from one of the lower houses.
There's nothing notable about the sandwiches here. The ingredients aren't particularly fresh, the flavours aren't all that bold, the price isn't competitive... the only real draw is the location.
Bonus: there aren't any tables in the restaurant, so I asked if I could eat by the counter. They said no :(
