If you liked the Aria the Natural anime, the Anime-Planet community thinks you'd like:
In a quaint Japanese town, far from the footprints of tourists, an abandoned robot named Alpha lives a quiet life, while running a coffee shop left by her previous owner. With hardly a customer from day to day, she tends to focus on life's little pleasures, while sporadically wishing for her master's return. But one day, a delivery-robot brings Alpha a camera, and through the pictures inside, her eyes are opened for the first time to the world around her.
Yokohama Kaidashi Kikou and Aria the Natural are two shows about absolutely nothing. Both have pretty graphics and music. Warning both may cause drowsiness. If you liked one you'll probably like the other.
