I found this on Crunchyroll but there are episodes on YouTube.
The first season is an adorable 2 minutes about a young woman who loves going out to eat alone. She finds the perfect pairing of food and drink she makes a happy little "pshuuuu" It's pure sunshine.
The second season is live-action. I've only see one of those, but my favorite part is that they take time at the end to say "Hey. This is where she ate in the show, these are the cooks, here is the address and the hours." It's so pure.
