We spoke to the creators of menurescu, and it is no longer actively maintained. However, they said that we are welcome to create a PR against their public repo to hit our backend endpoints to automatically populate their website. We'd need menurescu to hit api.sendchinatownlove.com/sellers and filter the response to make it look something like https://github.com/danielmichaelni/menurescu/blob/master/public/data.json

We can create a PR against menurescu and they'll approve/deploy it for us
