The team behind Abejas in Golden unveiled Nosu Ramen this week, which ladles up five kinds of ramen as well as donburi bowls and small plates. Along with classic tonkotsu and miso ramen bowls, there's also duck ramen, shrimp and kimchi ramen and karaage (Japanese fried chicken) ramen. This makes the third Golden eatery for the Abejas group, which also operates SurMesa Taqueria inside Tributary Food Hall.

Lupita's, an Aurora favorite for Mexican food for 25 years, closed last March at 11809 East Colfax Avenue. Almost exactly a year later, the owners of El Coco Pirata launched a new restaurant called La Machaca de Mi Amá in the old Lupita's space; it specializes in the food of Culiacán, Sinaloa. While El Coco Pirata focuses on seafood and Sinaloa-style sushi, La Machaca covers more land-based, home-style fare, including breakfast dishes. Exact hours have not been posted, but more details (including menu items) can be found on the restaurant's Facebook page.
