Best Live Music Restaurants in Diamond Bar

Very friendly service, interesting and very good designed inventory, terrific view!

The food was outstanding. Service was excellent. It was quite loud however. It was hard to hear someone speak across the table. The views were lovely. Gorgeous decorations. Valet service was good as well.

There were just 3 of us to celebrate a birthday. My two table partners ordered the special of the day-Alaskan halibut. They were perfectly cooked and a good size portion. I ordered the rack of lamb and they cooked it to a perfect medium rare. Our server was attentive, but not intrusive and surprised the birthday girl with dessert! A very nice evening. Looking forward to going back.

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!!

Absolutely loving the place and highly recommended.
