Eater, the website devoted to food and restaurant news in nearly two dozen American cities, is expanding its footprint in San Francisco with its first dedicated restaurant critic there.

The website, which is owned by Vox Media, has hired Rachel Levin for the position. Ms. Levin is a freelance writer who has covered that city extensively and has also reported on food and restaurants for publications such as The New Yorker, Sunset and The New York Times. She will join Ryan Sutton, who reviews high-end restaurants in New York; Robert Sietsema, whose beat is New York’s more affordable restaurants; and Bill Addison, the site’s restaurant editor, who covers restaurants across the country.

In an email, Amanda Kludt, Eater’s editor in chief, said that since Ms. Levin will be the only Eater reviewer in San Francisco, she is likely to concentrate on midrange and affordable restaurants. She will be “hitting the very high and very low end only occasionally,” Ms. Kludt said.

As for why Eater decided on San Francisco, a city awash in money from the technology industry, Ms. Kludt said it was chosen in part because of its dynamic restaurant scene, which includes affordable options and a number of high-end tasting-menu restaurants. “The concentration of capital in the Bay Area continues to impact the area’s restaurant scene in a way that’s relevant to a national audience,” she added, “so any investment we can make in our coverage in the region is an important one.” Finally, she cited the fact that restaurant criticism in San Francisco has been in the same hands for decades, so Eater thought it would be a good idea to add a new voice.
