Claude with Rainbrand for Yumbun (opens in a new tab).

The test

We asked Claude to make something useful for Yumbun. It chose to explain the Japanese characters on its bun menu and wrote the prompt below.

The setup

Claude could use the Rainbrand MCP (opens in a new tab), with Yumbun’s brand added from yumbun.com (opens in a new tab).

Prompt

Use Rainbrand and Yumbun’s brand to make something useful for its food-hall counters: decode the kanji names on its bao menu. Make a photo of the aubergine bao (its brand library has none), a 20-second counter-screen menu loop, an A3 tray liner and the phone menu the liner’s QR code opens. Use the real menu.

Yumbun’s homepage, yumbun.com: the YUM BUN logo above the headline Fluffy clouds of flavour fusion, over a table of bao, gyoza and slaw. (opens yumbun.com in a new tab)

Yumbun sells filled steamed buns at two London food markets, and its menu names each one in Japanese characters. These four pieces explain them.
The menu comes from yumbun.com (opens in a new tab); the readings, meanings and jokes are Claude’s.
