I loved the Shack Stack ($14.30), but was it really the "best of both worlds"?

One cannot deny that the pillowy potato buns and Angus beef patty were excellent in their own right, but they were no match for the juicy fried portobello mushroom.

Get the 'Shroom Burger ($10.80) so that you can, even if only for a moment, slip into molten cheese-induced ecstasy. Vegetables reign supreme after all.
