Bun Bo Hue is by far my favorite Vietnamese dish and my go-to whenever I see it on the menu. Bach Yen was special in that they have different spicy levels, something I've never seen before. I asked the guy what level he recommended and he said people usually get "medium" although it's still very spicy. Which I thought was weird that it would be a medium if it was considered very spicy. Long story short, he was right. It was delicious but probably the most spicy Bun Bo Hue I've ever had. Was so thankful I didn't go above "medium."
