I went with my family to this restaurant just in front of Centre Pompidou for a Sunday brunch. It is big and nicely decorated, with a main room with plenty of beautiful tables, but also a mezzanine where you can find a more intimate atmosphere.
In our case we were placed in the main room, which was handy, as the brunch consists of a full buffet that includes several types of cold cuts, pasta, chicken, vegetarian dishes and any type of cheese you might imagine. There is also a plate with eggs that comes directly to your table, salads, and an amazing array of desserts. We were there with some teenagers and it was really a good choice as they are always hungry, but the quality of food was exceptional. The kitchen is just behind some glass, which is nice, as you can see how the cooks are working and that all products are fresh. I strongly recommend this place for a long meal on a Sunday.
There’s also the “all you can eat” brunch from 11:30 to 16:00 on Sundays (on other days the place is also nice, as a normal restaurant or bar). 30€ per person. It is advisable to book a table.
