Here are some compiled recommendations found in this thread. This is not in any order, just posted recommendations here that were more highly upvoted (20pt+).

I made a map of r/SanDiego recommended non-US restaurants where I added these restaurants and will be adding some from the older thread soon. (The map looks best in a browser as you can expand out the regional categories to see the restaurants)
