If you are a fan of Haru in the Back Bay, you may be interested to hear that their “Mystery Envelope” promotion has returned. If lady luck is on your side, stop by Haru now through May 1st to receive your mystery envelope, while supplies last.

Bring the unopened envelope on your next visit to Haru Boston before May 20th to see if you’ve won. You could win Haru gift certificates, complimentary sushi rolls, or even up to $500 in AMEX gift cards.

Even if your envelope does not contain a prize, you will still receive a complimentary order of edamame as a thank you gift for playing.

For more information and official rules, please visit Haru’s webpage.

How fun! Good luck if you decide to play!
