Let's start with the obvious! Laduree is the queen of macarons. And macarons are a must in Paris. I went to the Laduree on the Champs Elysees for my 24th birthday, and it did not disappoint. The space is beautiful, the service was great, and it was an outstanding experience.
The menu consists of macarons, tea, and food (I didn't try the food, but I did get macarons!) It is pricier, which is to be expected. Upon entering, Laduree, you're able to view all the macarons on display and pick them up to go, or you can sit in the dining area, which is on the first and second floor.
Georges Larnicol - they have 3 locations in Paris. You can't miss it, the store is as pretty as the product. They have a lot of macaron flavours to choose from, as well as chocolate treats, meringues, and pastries. These macarons are very affordable too! They have a lot of chocolate art in store, which is very cool to check out.
Oh, Angelina. I have no pictures here, but this tea room is an exquisite place as well. Their macarons and pastries are beautifully crafted, and the cafe itself is breathtaking. Angelina is also a must-visit.
