Best Steakhouses in Diamond Bar

Absolutely outstanding service food was amazing and it's in a great location valet in the hotel was ideal

Good first time experience for me and my wife food was really good and the bar area was a good vibe with great music

My husband, daughter and I had Christmas dinner at Mastro's. It was so crowded, I would have totally understood if the service or food was lacking... but to my surprise, everything was perfect! Service was amazing, food was just as wonderful as always. The restaurant was lively and festive. Once again, dining here was a great experience. Definitely pricey, but worth it for a special occasion!!

This was my first time dining at this location, and I’m so glad it was open on Christmas Day. My family will make it an annual tradition to gather at Morton’s on Christmas Day. The food and ambiance were delightful.

Beautiful restaurant and ambiance. Service was perhaps best we have ever experienced. This really is a steakhouse so be aware that other entrees are limited. I ordered the cod and it was very good. Another in our party ordered a steak and she said it was perfectly done. Location is very good next to the beautiful Pasadena city hall. There is ample underground parking with some validation by the restaurant. I definitely recommend this restaurant for those that want red meat.
