When I was in LA recently, I spotted sardine banh mi but didn't get one. Much to my surprise I now see that Les Baguettes in Eden Center has both sardine and tuna banh mi.
The sardine version is excellent. It's a slender, tasty sandwich. If you want hot peppers, you'll have to ask. The bread here light and crispy and makes forr a better sandwich than a crustier version. This made for easy eatin'.
