My group of 19 coworkers had an absolutely fantastic breakfast at Cafe Mason on September 23! The food was delicious, with generous portions that left everyone satisfied. The service was outstanding—attentive, friendly, and prompt. Despite our large group, the restaurant accommodated us seamlessly, seating us in three neighboring booths, which made the experience even more enjoyable. The location was perfect, just a short walk from our hotel. We loved it so much that a few of us returned the next morning! A special shout-out to our server, Alex, for his exceptional friendliness and attentiveness. Highly recommend Cafe Mason for a top-notch breakfast experience!

Absolutely delighted to find this place during my recent trip! It's open early, the food is delicious (try the avocado benedict) and the coffee is nice and strong. My server, Alex, was wonderful and attentive, and his friendliness is why I went back a second time! Saved for my next trip to San Francisco.

Our meal was delicious and the Salomon Benedict was heaven. The pictures speak to the mean. Look at that fruit. Beautiful. Great coffee and excellent service
