To get to Atre Main Building, go out of the JR Ebisu Station East Exit ticket gate and you'll see the entrance on your left.
The Atre Main Building East Area is located just up the escalator in front of the East Exit ticket gate, where there's a seating area called Fontaine Plaza.
Around the central object, there are 8 round stools, a circular bench for 6 people, and 2 wooden benches for 3 people each.
There are plants in the object's aquarium, so you can enjoy the sound of flowing water and the healing effect of the greenery.
Also, the chairs installed around the object have a slightly unusual design, with flat plates on the sides of the legs.
It has a nice atmosphere, which is typical of Ebisu, but it might not be very relaxing when crowded because the seats are packed together.
However, since it's located right near the station ticket gate, it seems convenient for meeting someone in Ebisu.
Also, Atre Free Wi-Fi is available within the Atre building.
It's convenient to remember this when you want to use free Wi-Fi in Ebisu!
Why not use it as a place to take a break and sit down in the Ebisu area while you're shopping at Ebisu Atre?
