111 boulevard Beaumarchais, Paris.
Merci has been on my to-do list for ages, so I was so happy to finally go in not so long ago. It cannot be defined as a 'shop', as I think it is more of an experience, with so many parts to explore. The entrance to the shop itself is wedged between two of its three cafes, and walking through the archway you find yourself in a delightful courtyard, with their iconic red fiat 500 in front of you. Continuing through the door there is a wonderful mix of clothing, jewellerey, home and beauty products, all of which are completely different to what you might see on the high street. They have three cafes for you to choose between after your shop - the used book cafe; the merci canteen; and the cinema cafe. I visited the used book cafe and I was not disappointed - the staff were so helpful and the food and drinks were delicious.
Keep an eye out for... the beauty department - they have plenty of testers which all smell amazing and look so sleek lined up on the shelves.
