No more foie gras dinners, croque monsieur sandwiches or marinated beet salads.

East Bay chef-entrepreneur John Marquez — who has been juggling two East Bay restaurants for six months — has closed one, his Artisan Bistro in Lafayette, where he had served seasonal California-French fare since 2009.

Going forward, he will concentrate his efforts on Lima, his Peruvian place that opened last November in Concord.

A spokesman said Thursday that the reasons were twofold: It had become increasingly expensive to operate Artisan, especially with the rent, plus Marquez wanted to devote more time to Lima.

A native of the Peruvian capital who grew up in Danville, Marquez brought a rich résumé to both restaurants: In Peru, he trained with noted chef Gaston Acurio. In this country, he worked with chefs Julian Serrano (Picasso, Daniel Patterson (Elisabeth Daniel, Coi) and Thomas Keller (French Laundry, Per Se) before opening Artisan Bistro.
