I found this fantastic spot for Bò Né after passing it on my bike one day. It seems to be busy every night with a great atmosphere.
Make sure you order Chén Bò, a bowl of thinly-sliced beef in oil and butter which cooks over a flame at your table. It's seriously good!
I prefer to order the simple Bò Né with 1 egg, beef & paté with a side order of the Chén Bò.
Recommended but definitely not healthy!
