Tacos, beer, wine – you really can get your fill this San Diego weekend, especially in Rancho Bernardo. Also, listen to a hyphenate star (actor, musician, etc.) explain why he added author to his long resume.

That would be Oscar-winner and comedian Jamie Foxx, who visits El Cajon’s The Magnolia at 8 p.m. Friday to promote his new book, “Act Like You Got Some Sense.” The local stop wraps up his five-city book tour – and big-star sighting, times two – Foxx is ending it with a splash as rapper Snoop Dogg is set to moderate the discussion. Admission starts at $49.50.

Can you say road trip? Head out east as the local Chamber of Commerce brings back the two-day Borrego Days Desert Festival at Christmas Circle at 10 a.m. Saturday. The free event includes an opening flyover, talent show and live entertainment, including San Diego Music Award winner Whitney Shay.

Fall brings the scary, but there are spirits to celebrate too. With Dia de los Muertos in mind, the San Diego Botanic Garden opens the Festival de Otoño Saturday with live music, crafts and artist Katie Ruiz’s ofrenda, an altar for remembering lost loved ones. The garden invites you to bring items to share at the altar. Look for pumpkins near Hamilton Children’s Garden, along with seasonal photo ops. Admission costs $18 for adults, and $10 for youngsters.

Tacos, of course, should never be confined to Tuesdays. Chow down at SoCal Taco Fest at Waterfront Park beginning at 11 a.m. Saturday. Entertainment includes Flo Rida and local favorites the B-Side Players, with some quirky fun too, like a chihuahua beauty pageant. Admission, $45.

Want a weekend soak in the suds? Try the Rancho BEERnardo Festival at 2 p.m. Saturday. Who’s on tap? Try AleSmith, Alpine, Alvarado, Xteca, Karl Strauss, North Park Beer Co., Resident, SouthNorte, Mason Ale Works and Wild Barrel to name a few. Webb Park in Rancho Bernardo plays host – a $65 ticket gets you unlimited 2 oz. pours, plus live entertainment. Eats are extra.

San Diego Opera opens its fall 2021 season Saturday with a Balboa Theatre recital starring mezzo-soprano Stephanie Blythe. Her show, “Johnny Mercer: America’s Lyricist,” focuses on the works of the prolific late songwriter whose tunes you’ve undoubtably heard in a movie or two. Try “Moon River” and “Hooray for Hollywood” to start. Blythe performs at 7:30 p.m. and admission starts at $45.

The Rock ‘n’ Roll Marathon returns to action bright and early Sunday, beginning in Balboa Park before slicing a path through neighborhoods from Mission Bay to Normal Heights. Sure, there will be lots of temporary road closures, but make the most of it and cheer on the runners. There’s free entertainment throughout the course to enjoy too.

Like to keep your beers and your wines local? The Bernardo Winery hosts the San Diego County Vintners Association Wine Festival at 1 p.m. Sunday, featuring an all-San Diego lineup of vino. Try vintages from Beach House Winery, BK Cellars, Gianni Buonomo Vintners, Highland Valley Winery, Koi Zen Cellars and many more. Tickets, which cost $80, include unlimited tastings and small bites too.
