- AAaronGoldSan Francisco Bay Area •1 review5.0Dined 1 day agoMy girlfriend and I had an absolutely phenomenal experience at Mastro’s! From start to finish, everything was exceptional. The food was exceptional. Every bite exceeded all our expectations. The food alone made this one of the best dining experiences we’ve ever had! Our waiter, Pedro, was incredibly attentive and professional, and the entire wait staff went above and beyond. From keeping our water glasses filled and clearing the table to carefully packing our leftovers, every detail was handled perfectly. We also appreciated being seated at a spacious four-person table, as we love sitting next to each other when dining out. The staff made our anniversary even more special with a lovely anniversary dessert, which was such a thoughtful touch. Between the phenomenal food, beautiful atmosphere, and outstanding hospitality, Mastro’s truly set a new standard for us. A huge thank you to Pedro, the management (Brian and Andrew), and the entire team for making our anniversary unforgettable. We will absolutely be back!More infoMastro's Steakhouse - San Francisco$$$$• Steakhouse• Downtown / Union Square•4.6

- SscottSan Francisco Bay Area •1 review5.0Dined on Oct 27, 2026Absolutely wonderful experience. Great service, nice wine selection either by the bottle or glass, the Truffle Fries were an amazing indulgence, and the steak was exceptional. We hesitated at desert but finally shared an ice-cream and I think it was homemade - terrific. Highly recommend!More infoUla Restaurant & Tapas Bar$$$$• Tapas / Small Plates• Financial District / Embarcadero•4.2
