It’s also fine for a different “connoisseur” to enjoy store-bought California rolls made from imitation crab and left sitting on a shelf until the rice is stale.
It’s overly reductionist and pretty patronizing to insist that the former doesn’t really like sushi while the latter does (No True Scotsman, and all that).

P.S. The mainstream brands of Mexican beer are pretty good. Most of the big Mexican breweries were started by German immigrants in the mid-19th century, and there is now a long beer tradition there. Corona’s extensive marketing to the US about tropical getaways and lime slices, etc. has nothing to do with their product or their brand in Mexico, and I find it fairly silly, but it was extremely successful.
