Where to take a food enthusiast from L.A.

Hi hounds. Been a while. This new site is weird.

I have a hardcore food-head coming in from L.A. and I want to show him something special here in Boston. What do we have that they don't? I am not so much into trendy or fine dining, more interesting, passionate or ethnic.

My first thought is Simply Khmer. I don't know of a large Cambodian population in L.A. and that food is amazing.

I don't think we can do better with Mexican, Japanese, Chinese, Vietnamese, Korean or Thai than L.A.

Any thoughts?

Thanks!
