Or ya' know it might just be things like:
The tacos were often poorly reviewed, mostly due to soggy shells...
Seafood has a shorter shelf life, and while the Poke bowls were well reviewed, they may not have been purchased enough to be cost effective to continue to offer...
And speaking of cost effective, if they're not selling enough specialty burgers (which made up a large part of the cuts list) then it's not cost effective to carry multiple types of meats,(or in one case, vegetarian fake meat,) for so many types of burgers, especially if one type of burger is selling more than all the other types combined.
It's been long enough to see what sells well and what doesn't. They've had a chance to watch how long things sit before being sold. And I'm sure they've been calculating how to save money by bulk ordering only the more popular things, and dropping the ones that sell less often, (even if they were well received.)
I for one am glad they at least kept some of the healthier/lighter options like salads and even sushi.
