Elephant & Castle Restaurant - $5 off any order - No Expiration - Located in major cities in USA/Canada
I received the coupon by signing up to receive emails here , but I have also attached a copy to this thread.
They have the usual sandwiches, burgers and salads - with a British pub flare. I haven't been there yet, but am definitely going to try it out now.
