For me the best vegetarian (vegan) restaurant in Dali Old Town.
The family that runs it are very nice and friendly.
The menu is very extensive and everything I tried tastes very good.
Most of the dishes are vegan except a few that have milk or egg. Be clear about that when you order if you are vegan.
I think is better to go 3 or more so you can try many different dishes.
It's a two-floor restaurant just outside Old Town from the South side walking on BoAiLu, just up the hill for 100 meters (YiTaLu).
Cons: sometimes not clear with no-vegan dishes
