Turtle Tower's pho comeback leads 2025's casual, walk-in-friendly Southeast Asian openings

Asked:

“What are the best new southeast asian restaurants in the bay area? They should be open since 2025, casual, and take walk-ins.”

From a researched candidate set of nine Bay Area openings, three clearly qualify: all in San Francisco, all opened in 2025, all casual and accepting customers without reservations. “Takes walk-ins” means no advance reservation is needed — not a guarantee of no line. Each entry is single-sourced: Turtle Tower directly from Eater editorial, the other two from Postcard aggregation.

Turtle Tower is the strongest all-around match: casual counter seating, walk-ins explicitly accepted, and Eater-praised pho ga with a clear, soothing broth — sf.eater.com

Fikscue serves its Indonesian–Texas barbecue from noon only until supplies run out — go early or it may be gone — postcard.inc

Señor Sisig at Thrive City is the easiest event-day pick: no reservations needed, though fried-to-order sinigang wings can mean a short wait — postcard.inc

Source quality differs: Turtle Tower's details come straight from Eater's review; Fikscue's and Señor Sisig's service details rest on Postcard aggregation — sf.eater.com

Before you go

Turtle Tower — walk-ins accepted, but groups should expect a wait at peak weekday lunch. Fikscue — the sold-out risk is real: service starts at noon and ends when supplies run out, so treat it as a lunch, not a dinner. Señor Sisig — food is fried to order, so a short wait is normal; plenty of TVs while you do.
