Free food is earned by collecting "tokens". You earn 1 token for every purchase over $15, before taxes, up to a maximum of 1 token per order. Collect 6 tokens to get 1 free meal reward!
For tokens to accumulate, order information and preferences to be saved, you must have a My Edo Rewards account and use that account to order each time. You can order though edojapan.com or the My Edo App.
