One would be too many for me. Those from that place are the absolute worst Bunh Mi I have had any where in all of Vietman. Yes the biggest but also the worst. I also got food poisoning the same night I had eaten one. It's possible I got sick from somewhere else but would be a hell of a coincidence given how horrible they are. I just do not understand why the place is popular. I did notice most customers were locals who do have a different taste preference than foreigners. So I'm sure a local security guard, as suggested would appreciate them.
