This brand new Starbucks is awesome. While there are only a couple of wall outlets, the interior design makes up for it. Lots of natural light from the windows, lots of beautiful furnishings, cozy, seating areas, and tables to meet up or get work done. They’ve thought of everything. Parking is easy. And the staff are extremely friendly and helpful. I highly recommend this Starbucks.

Thanks to the beautiful long hair lady who gave my dog some water and kindly let me go inside to order coffee with him. He’s a bit crazy—if I tie him outside, he acts like a mad dog .

Don’t know why I can’t write another post, so I put here. Today is 20260219.
I came through the drive-thru around 6:55 this morning to grab my coffee.
Your sincere, friendly service and warm smile made me feel like a star at the start of my day.
As a working mom juggling work and childcare, I had just left home with my child in tears. It was a tough moment. Your warmth, along with that comforting cup of coffee, truly felt healing and brought me so much comfort. Thank you so, so much — I truly appreciate you. A soft-spoken, slim young lady who looked like a college student.❤️❤️❤️

I happened to be in the general area (Diamond Bar) and had several Starbucks to choose from. I specifically went out of my way to this one as it is the newest location within 2 to 3 miles.
The person whom took my order was Sam (Samantha), she was nice and friendly (as were her coworkers) and got me squared away quickly. I was doing too much chatting and she was kindly tolerant while managing listening to me and communicating in her headset.
As far as the location…it’s in an equally new shopping center area and this particularly Starbucks location has a very nice dining area. Plenty of seating and gathering areas. I didn’t bring my phone in to get pictures but another person in the review section did a great job getting pictures.
I was told that while it can be busy in the evening that it still remains rather quiet. The seating and table placement as well as the couches are in close proximity to each other. That can be annoying if you have the loud obnoxious types whom are not aware of their surroundings. Something to consider ahead of time – if you’re looking to scope out a spot to minimize the chance of encountering that type.
Overall, it’s a nice location and worth visiting if you’re in the area.

Went in for a quick coffee and a bite to eat while driving through the area. Friendly baristas. Clean and well designed with lots of seating. Wasn’t crowded at all on a Friday evening. Definitely would visit if I happen to be in the area.
