I’d like to join in welcoming you to San Francisco!! looks like you will be enjoying Cinderella weather, not too hot, not too cold. I personally think this time of year is the best time to visit The City.
A few of my suggestions, with the caveat that we just don’t dine out much anymore. Even before the pandemic. These are restaurants that we’ve enjoyed in the past, and still visit periodically.
Mexican. Pancho Villa, 3071 16th St, San Francisco. A basic neighborhood taqueria. The ingredients are always fresh, prep is well done. Great help yourself salsa bar, love their tomatillo salsa verde. Our usual order is a burrito and 3 tacos. With Carnitas (braised pork) and/or Lengua (beef tongue).
Swan’s Oyster Depot is a popular go-to for many visitors. The queue can be a couple of hours long, be forewarned.
For a taste of San Francisco seafood prep, we like Sotto Mare, 552 Green St, San Francisco. Neighborhood seafood restaurant in North Beach, thus with an Italian bent. The Cioppino is very good. Had some great Swordfish steak, just before the lockdown. Pastas are very good as well.
Tadich Grill, 240 California St, San Francisco. A couple of blocks away from the Regency. Old school (real old) restaurant fits your local institutions request. Great Sand Dabs, Sourdough bread baked to their unique specifications, huge martini’s. A menu that covers both seafood and steak.
Scoma’s, 1965 Al Scoma Way, San Francisco. Another SF seafood institution. Food is a touch spendy, but the restaurant has had decades to fine tune their menu and service.
House of Prime Rib, 1906 Van Ness Ave. Still the best place for a meat-centric dinner, for me. Great meltingly tender Prime Rib (aged beef), OG tossed salad, sourdough rounds, creamed spinach and Yorkshire Pudding. With a couple of martini’s to start, and a full bodied red with dinner. One of my favorite dinners.
Chinese Dim Sum. Great Eastern, 649 Jackson St, San Francisco. Old old school. Not exactly nouveau Hong Kong current, but still good enough to scratch that Yum Cha itch. Obama stopped his motorcade there in 2012 for takeout.
R&G Lounge, 631 Kearny St, San Francisco. Well prepared Cantonese restaurant doing some fine cooking. We like their Drunken Pigeon, Whole boneless fried chicken stuffed with glutinous rice (pre-order), and their double boiled Cantonese soups.
I hesitated to add the Ferry Building farmer’s market on Saturday morning, since there are so many great farmer’s markets on your side of the pond. If you do happen to be wandering around Saturday morning, the market is a mere block away. You can drop by for a cup of Blue Bottle coffee, and a pastry from Acme Bakery. Or maybe a half dozen oysters at Hog Island Oyster Co.
Since you are only free one day, tried to keep list to generally walking/short Uber distance from the Hyatt. Glad to add more if you have more ideas. Have fun, should be a great time.
