i recently discovered that costco offers a bbq beef brisket sandwich. i think it is the default to the pseudo shake shack burger being offered only in pacoima, lakewood & corona.
which i thought was ok, but not worth driving out to pacoima, lakewood, or corona. anyway, the sandwich comes in a cardboard cylinder (which i neglected to photograph, which holds in all the beef which can then slide out after you take the first bite. i gave up and used a knife and fork.
the brisket texture was pretty good, the cole slaw a bit too sweet, it would be much better as a pulled pork sandwich with a spicy vinegar mop IMO. the BBQ sauce was totally underwhelming.
