My favorites in order:
1. Lotus Garden (Mission and Valencia)
2. Angkor Borai (Mission near Valencia) I know it's not Vietnamese, and the filling is a little different (pork ground rather than sliced) but they do a really good job and it's the same flavor combo as the Vietnamese versions.
3. Bodega Bistro: Usually good, but sometimes they're too thick and
undercooked so they're gummy. They are in the tenderloin though. (Larkin near Eddy)
Not sure if Bodega Bistro is open for lunch. I've only been at dinnertime.
