Sometimes you've just got to take a leap, plans be damned.
That's what some spontaneous Dublin diners did when they ordered the 'Thursday special'. It was all a bit mysterious and this was their only clue.
Fly blind with a selection of underground culinary delights, each more intriguing than the last.
The result was them being whisked off - blindfolded - to an exclusive Heineken 'Dine in the Dark' event at Christ Church Cathedral.
Would you order the special?
The next #OpenYourDublin event is 'Lost & Found', a Dublin treasure hunt taking in some of the city's hidden gems. It all concludes with music from Cloud Castle Lake and Mmoths in a secret final location.
For a chance to win tickets for 'Lost & Found' tweet - @Heineken_ie and state which chef Andrea (one of the spontaneous diners in the above video) speculates might be at the event.
