Last night we were pleased to see several empty tables at Shake Shack, around the perimeter of the garden. It didn’t take long to find out the reason: At least three mice kept emerging from the plants and approaching tables like beggars (seriously — one got within a foot of us before we scared it away). Three or four parties cluelessly sat down only to notice the furry fiends and either moved their tables away or scampered off with their tails between their legs. Of course, this isn’t anywhere near as scandalous as a chef caught tonguing toads; Shake Shack is located in a public park, after all, and mice have been spotted before, but if this video of two of the lil’ fellers butting heads succeeds in scaring off just one or two squeamish tourists and the line thins just a tiny bit, well then Grub Street has done its civic duty. Meanwhile, the Daily News reports that the Shack is in talks about a Coney Island location.
