Instructions:You have to 'join the club' by entering your name, email address and which slug and lettuce restaurant is closest to you (the one you want to eat at) and then all you have to do is print off a voucher.
The voucher entitles you to £5 off your meal (food not drinks) with no minimum spend, and if every person in the group has a voucher they should all be accepted.
No waiting weeks for it to come in the post.
My voucher is valid for 14 days.
Cannot be used in conjunction with any other offer or promotion.
Direct from the slug and lettuce website.
For use against food orders, not drinks.
I'm going out this evening and plan on using my voucher. If any issues I will post.
UPDATE - worked a treat, no problems, 2x vouchers used for meal for 2 people. You have may have to pay separately, depends on your waiter!
Minimum spend now £10 and you have to make a reservation online for the discount to be valid.
