- dishesWe stumbled upon Mason Diner Café during our visit to San Francisco, and we ended up coming back multiple times—it was that good. The food is absolutely fantastic—every dish we tried was flavorful, fresh, and served with care.

- serviceShe took the time to get to know me, showing genuine interest in understanding my preferences. Her warm and attentive service truly stood out, especially compared to the rushed and impersonal service often encountered elsewhere. Nina’s dedication to creating a personal connection made my visit memorable; she’s an absolute gem!
- AlexFull of a lot of tourists who were curious about one thing or the next, as tourists are. The proprietor Sarah was friendly and shared anecdotes; the main fellow who served me, Alex, was most helpful with all things about the city, the service, the food and a little history of the place -- 32 years in the making! "All from scratch" and with generous portions.
- staffMy experience at this restaurant is always great. The food is great, the atmosphere is very comfortable and clean, and the staff are some of the friendliest you'll find. A special shout out to Alejandra, Alex, and Nina who always remember me and greet me with a smile!

Frequently criticized
- serviceI went to have breakfast with my husband and was seated. However, we were ignored for at least 20 minutes without even being asked if we wanted something to drink. This was despite people who came in after us receiving immediate service.
- staff memberstaff member was very rude and dismissive
- treatmentThe server provided no effort to provide decent service and seemed generally uninterested in assisting us. To make matters worse, we were asked to leave our table while still finishing our coffee, which is unacceptable treatment for customers. I cannot recommend this place.
- Spanish male waiterThe Spanish male waiter was very rude
- apologisewhen we ask them to correct the bill they didn’t apologise
- customer servicepoor customer service
- denied serviceOn February 2, 2024, I was denied service at Café Mason. I ordered food and coffee, and was served the coffee.
- discriminationThis experience of being denied service significantly affected my health and caused me distress. I do not understand why I was treated this way and believe I was being discriminated against.
- explanationhe did not give an explanation why

Excellent Diner Experience with Great Service
Since the diner was located right next to our hotel, we decided to have breakfast there. Our waiter, Alex, was extremely accommodating and friendly. We had the Granola, a Croque Madame, and Eggs Benedict with Hashbrowns.
We found the taste to be very good, and the portion sizes were also exceptionally large. The coffee was typical of what you'd expect in an American diner. As it was my fiancé's birthday, he was even surprised with a birthday song and a scoop of ice cream.
An absolute recommendation, and many thanks again to Alex!
