Bar Esper Opens in San Francisco With Portuguese Japanese Fusion Dining
SAN FRANCISCO, CALIFORNIA — San Francisco’s fusion culinary scene recently added one of its most unique combinations.tions yet.
Bar Esper has quietly opened inside Hotel Spero in the Tenderloin, blending Portuguese comfort food with Japanese ingredients and techniques in a way that feels both unexpected and surprisingly natural.
The restaurant officially debuted on May 20, taking over the former Jasper’s Corner Tap site with a newly renovated concept centered on robust flavors, drinks, and late-day dining.
What’s New
Bar Esper arrives at a time when Japanese fusion concepts are expanding rapidly across San Francisco.
Unlike the city’s expanding wave of Japanese-Italian or Japanese-Peruvian restaurants, Bar Esper focuses on Portuguese influences, serving dishes like linguiça, malasadas, and peri peri chicken alongside miso, udon, milk bread, and black garlic aioli.
The restaurant occupies a large street-facing dining room with seating for around 110 guests, and the space underwent a major renovation before opening.

Unlike many hotel restaurants that feel detached from the city, Bar Esper plainly aims to attract both locals and hotel guests, particularly theatergoers and evening throngs passing through Union Square and the Tenderloin.
Menu & Experience (with POV)
The menu at Bar Esper feels built around contrast.
There’s Japanese expertise layered onto Portuguese comfort cuisine, resulting in dishes that appear strange on paper but make a lot of sense when you see the combinations.
Standout menu items include:
- Pork katsu breakfast bowls
- Spicy crab yaki udon
- Peri peri chicken
- Shrimp dumplings
- Duck-and-chorizo rice crisped in a paella pan
- Steak prego sandwiches with miso mustard
- Ebi katsu sandwiches with shrimp, cabbage slaw, and peri peri chili crisp
Lemon matcha curd malasadas, pastel de nata pastries, and tamago breakfast sandwiches stacked with linguiça or chorizo are also popular breakfast options.
And throughout nearly everything? Black garlic aioli.
From my perspective, that ingredient alone sounds like it could become the restaurant’s signature. The menu is definitely not aiming to be subtle; it leans heavily on rich, deep flavors that feel meant for sharing and conversation.
Community Buzz
Part of the excitement around Bar Esper comes from the people involved.
Legendary San Francisco bartender Jacques Bezuidenhout, who has worked at Wildhawk and Tres Agaves, helped create the cocktail program.
The drinks menu focuses heavily on Japanese spirits mixed with Iberian influences, including Madeira wines, calvados, and fortified wines.
At the same time, the opening symbolizes something larger for the Tenderloin itself.
The restaurant is essentially betting on the neighborhood’s continued recovery and nightlife return. During Jasper’s 15-year tenure, the location became known for industry evenings and bar culture, and Bar Esper is keen to recreate that atmosphere with a more contemporary identity.
Final Thoughts
Bar Esper feels like the type of restaurant that San Francisco still excels at: ambitious fusion dining that is nonetheless approachable.
Instead of blending cuisines for novelty alone, the restaurant seems focused on finding common ground between Portuguese warmth and Japanese precision.
And honestly, in a city where diners constantly chase something new, this might be one of the more interesting combinations to arrive this year.
If you’re in San Francisco, Bar Esper is a must-visit, especially if you enjoy restaurants that are difficult to describe.
