He is NOT a Zen Buddhist. He's a Christian who's taken a self-imposed vow of silence because he believes that when we talk, we don't listen, and our ego gets in the way of love toward humanity. He challenges our dividing language by calling us Humanese. And he sincerely hugs every person who enters and leaves. He has the gift of making every person feel special and that they are his favorite person. The food reflects his love and peaceful life.
Yes, the service is spotty at times. But the staff, mostly young Vietnamese immigrant students who are also going to school full-time, are trained (or not trained) minimally by the owner who doesn't even assign them to sections. Thus, with random servers stopping by to take orders and deliver food, the service suffers.
However, it is the BEST raw restaurant ever. I have been to ALL of them in California. All the raw food chefs/owners/personalities gravitate there when they're in town for a reason.
The Vietnamese cooked food may not be up to par; I have no idea. But the raw menu is thorough, tasty and highly unusual. You'll find no faux pizza here!
