Sometimes I have FOMO about not living in LA (which has, I think better food in nearly every cuisine), but I follow the guy who’s in the news as ‘guy who’s eaten at more than 10 000 Chinese restaurants in America’ and he thinks at least Bay Area has way better dimsum. I think I agree
However, Monterey Park / San Gabriel Valley is maybe the most exciting place for any East Asian food on this coast in this country (and Queens in NYC).
Monterey Park and Queens account for pretty much all of recent Chinese immigration to this country
