Jorge Sanchez, the Puebla, Mexico, native behind the Taco Mix taquerias in East Harlem, has opened his first sit-down location in Riverdale, in the Bronx. (He kept the previous restaurant’s name, FonteNova, out front.) For now, the brick-walled dining room with a stretch of bar is not serving guests indoors, but there are a few tables out front and a tidy little garden in back. Tacos al pastor, cemitas and tortas, like those served at Mr. Sanchez’s taquerias, anchor the menu, and his chef, Juan Gomez, is planning to prepare clams casino, shrimp in chipotle sauce, penne in a creamy marinara sauce with seafood, and stuffed chicken breast for a menu with Mexican and Italian seafood.

This Korean-American restaurant is from the team behind Osamil, in Koreatown. Pork belly confit with “burnt” sunchoke purée, and branzino with a kimchi vinaigrette, will be served. The restaurant is named after a satirical periodical published by the writer Washington Irving. (The term also refers to a mixed meat and vegetable dish, and is the name of an art club on Fifth Avenue at 11th Street.) A lovely tented, plant-ringed dining area in the street is what’s opening for now. (Opens Wednesday)

Suffering from the pandemic slowdown, two restaurants near each other have joined forces to serve the food of both on the same menu.

This branch of a Fort Lauderdale, Fla., restaurant is a newcomer to East Hampton, with a vast menu of Japanese, Thai and Chinese dishes. Worth noting are the fortune cookies with messages exhorting participation in the census. Examples: “Don’t be left out. You matter. Census 2020.” “You are not a bot. Be Counted. Census 2020.” “Do it for your community. 2020 Census.” “Eat me. Then be counted. Take the 2020 Census.”

Ravi DeRossi confessed to having too much time on his hands during the pandemic. The result? He has restructured his 16-year-old East Village dining and drinking empire, giving it this new name and making changes in several of his restaurants. “I went plant-based in all my restaurants five years ago, and it’s time for a name to reflect that we’ve become more mission-driven,” he said. He closed Mother of Pearl, Night Music and Honeybees. He is expanding his popular bar Amor y Amargo, and plans for it to share an expanded space at 95 Avenue A (Sixth Street), with a shop selling bar equipment and ingredients, to open in about a week. A new Filipino restaurant, Saramsam, will soon replace Night Music, which was Indian. Cadence, serving soul-food bar bites, will take over the space of Desnuda, a ceviche bar, which has closed. It will make its debut in a few weeks, depending on the pandemic restrictions. Mr. DeRossi remains a partner in Death & Co., a chain of bars in several cities that is not part of his hospitality group.
