  So good that we had to come back again in a week! Special thanks to Alex who served us, really energetic and nice person! Had a great breakfast here with my fiancé on our wedding day! Such a great start! Also the day when we left the city! Thank you San Francisco!

  Superb spot for breakfast, close to Union Square. Wonderful selection of breakfast staples, I visited it twice during my visit. Menu with Omelets, pancakes, sandwiches, and bowls. Great flavorful coffee. The service was quick, cheery. and very attentive. Refills of coffee was gratly appreciated.

  This was a solid breakfast choice. I got the Philadelphia cheesesteak scramble with hash browns. My wife got the mushroom Benedict, and my Mom got the blueberry pancakes. The food arrived amazingly quick and was pretty good. My wife thought hers was a bit bland but otherwise good. The atmosphere is very orange, but nice. Oldies music playing in the background.
  
  Overall it was a great experience. I didn’t really like them putting on the menu that 18% tip is “customary”. I’d prefer to tip based on experience rather than guilt. But I guess some people don’t know, so that’s fine. The experience was good, our waiter was entirely too enthusiastic. I would definitely come again.

  Mason Diner was a pleasant spot to grab a meal. The staff were friendly and welcoming which made the visit enjoyable. The food was tasty, though the portions were on the smaller side. The atmosphere was cozy and comfortable, perfect for a relaxed meal. If you are staying at HI Hostel next door, you even get a discount — just show them your booking. Overall it was a nice experience and worth a stop if you are in the area.

  From the very beginning, Aleks was exceptionally kind, maintaining a friendly and respectful attitude that made the entire experience even more enjoyable. His assertive communication reflects an excellent understanding of customer service.
  
  Aleks also works with remarkable speed, offered Great recommendations and handeld every request with a constant, genuine smile.
  
  Thanks to his exceptional service and the great Eggs Benedikt, I had a highly positive experience. Aleks is, without a doubt, a great asset to the team.
