    We had an 11:30 am reservation and we're the only ones in the restaurant. We got quick service and the food was delicious. We look forward to going back the next time we are in San Francisco.

    Our Christmas Day Brunch experience was fantastic. I have some food allergies so I had emailed The Post Room Team in advance and received a prompt, reassuring reply from the chef, Jose, who had clearly given my questions thoughtful and thorough consideration. On the day, I received personal service from Jose who was committed to avoiding issues with cross-contamination. All the food we ate was delicious and the dining room team could not have been more welcoming or accommodating. We were so well looked after, it was a faultless festive experience. We only went out for our Christmas meal this year because I had recent hand surgery and can’t cook much. However, our experience at The Post Room was so delightful, I am considering doing it again next year. Thank you to Jose and the whole team.

    Lunch after a matinee is one of our Holiday traditions- this year it was just perfect. The restaurant was packed with diners waiting for tables lined up at the bar, so thank goodness we had a reservation (on a Monday at 3:00PM- who knew?). Once past that minor inconvenience, everything was absolutely wonderful. We shared the Tortelloni appetizer and even though I am an accomplished Italian home cook, it was the best we have ever had. Then we shared the Jack LaLane salad - partly because we grew up with him on TV and the nostalgia was undeniable- and it was perfect. It had a respectable amount of seafood and avocado and was very large. My husband said his Manhatten was excellent. We left vowing to come back soon and often.
