Starbucks Coffee Company — Restaurant in Diamond Bar

Placed a drive through order for my wife on Wednesday morning, November 13, for a Vente peppermint mocha made with DECAF coffee with whipped cream. I got home and my wife tried the drink and said she couldn’t drink it because it was made wife regular coffee. She is very sensitive to caffeine!

She called this Starbucks and verified the location and explained the situation. the person at this location apologized and said they would mark their board with a credit for either me or our granddaughter who frequents this location at least 3 times a week. I went through the line Thursday morning , November 14, with my granddaughter for breakfast and a drink before school. I told the employee about the pending credit and she said they had no record of that. After waiting in the car line for nearly 1/2 hour we got to the window and the warm food was ready but not cold drink.

Been here twice already and satisfied with my experiences!

I have only ordered via mobile app and the drinks come out QUICK. The app is accurate--within 4-7 minutes!

Today I ordered a Venti Strawberry Acai Refresher with light ice and it was DELICIOUS. I am currently obsessed with their refreshers.

I am an iced vanilla soy latte fanatic so that made me a little bummed, but the drink with oat milk was still OK.

I have yet to order in person or through their drive through. But I am satisfied with the mobile experience! Thank you staff for what you do!! I plan to keep coming back and ordering via the mobile app again and again when I'm...

While I’ve previously had good experiences at this location, they’ve recently been struggling to keep up their quality and service standards. When my girlfriend asked for her drink to be made with soy milk, she was given one with normal milk which is a problem since she’s very lactose intolerant(hence the soy milk). She spent the next few hours in pain and had to skip class because of a barista’s simple negligence. An easy mistake to make, but a very dangerous one. Today I decided to give it another shot, but the soy milk used in my drink was old and chunky: pretty much undrinkable. Good Wifi, friendly baristas, but I would suggest that milk alternatives be stored and monitored properly in order to avoid serving spoiled goods. The importance of getting substitute ingredients right should also be reinforced to the baristas to avoid...
