There's some exciting news up in Pac Heights, where chef Matthew Accarrino has just opened a second restaurant around the corner from the stellar SPQR, and it's called Mattina.

Back in January, Hoodline had the early news of Mattina's arrival in the former Out the Door space (2232 Bush Street off Fillmore), but at the time the details were slim. Now, as Tablehopper reports, the restaurant is open for breakfast, serving a variety of sweet and savory treats, including scones, creative cookies, and a breakfast sandwich served on a house-made biscuit with San Daniele prosciutto.

See that assemblage below, complete with a little charcoal-grill toasting on the biscuit.

"Mattina" means morning in Italian, but it's also obviously a little play on Accarrino's first name. In the early pandemic, Accarrino had gotten into the breakfast game doing a pop-up called Accarrino's Coffee & Doughnuts, selling freshly fried, Italian-style bombolini out the door of SPQR.

It doesn't immediately look like the little doughnuts are on offer at Mattina, but time will tell. The restaurant website still features a "coming soon" message, and the place is still in soft-opening mode — with hours this week Thursday to Sunday, 8 a.m. to 2 p.m., and next week Tuesday to Sunday, 8 a.m. to 2 p.m. Hours will extend later in the afternoon and evening in late April.

"I wasn’t immediately planning on opening another restaurant in the city,” says Accarrino. "The space around the corner became open, and it just made sense... Mattina is my love letter to San Francisco, specifically to the Pacific Heights community that has supported my team and me over the years. I wanted to make a place, as a guest, I would always want to be. Something vital, useful and fun.”

Mattina will serve an all-day menu that will feature pastas — Accarrino is a master — as well as grilled spiedini (skewers), vegetables, and some larger-format items including a roast chicken, a whole roasted fish, and a 24-ounce ribeye steak. Below is just a little preview photo of the menu.

Also coming will be afternoon and evening aperitivo service or "Appi Hour," with a vermouth cart in the works — Accarrino has sourced over 30 varieties of vermouth, which can be served as spritzes or on their own. There will also be a wine selection with a "focus on affordable and mid-range options by the bottle and an extensive selection of wines by the glass, both of which will lean heavily on Italian producers," the team says.

SPQR, which remains open around the corner, is still one of the best and classiest Italian restaurants in the city, with a focus on Northern Italian wines and flavors — though Accarrino's pastas can run the gamut of many regional styles. It was formerly the sister restaurant to A16, but the two restaurants are no longer linked.

Mattina - 2232 Bush Street - Currently open Tuesday to Sunday, 8 a.m. to 2 p.m., with expanded hours coming soon. Aperitivo hours will be 4 p.m. to 6 p.m., and hours will ultimately be Tuesday to Sunday 8 a.m. to 9 p.m., starting in late April. Check for reservations on Resy.

This post has been updated throughout with details on hours and comments from Accarrino. A previous version of this article incorrectly stated that SPQR and A16 were still part of the same restaurant group.
