Starbucks - Diamond Bar

Cute location. Small seating area but bright and airy. Small seating area outside seems like you are right in the drive thru But the drive thru is great and very convenient Staff is super helpful and friendly. I had placed a mobile order and when I got there they said they could not complete the order as they had run out of matcha. The barista kindly offered to make me anything else I would like and he did it right away. That was nice.

Great Starbucks to study or chat. There's a good amount of tables with bar seating available. The staff are friendly but may be busy with the drive-thru orders.

It 's a hit or miss at this location. Ordered a Grande Flat white, got a cup that got probably 2 inches thick of not so fine at all foam on top. Rather if it 's the correct small cup of flat white or your Starbucks way of flat white, it should not have this much of foam. And it 's a 50% chance to get it made incorrectly here.

Everyone at this Starbucks was so friendly. I ordered a Vanilla Sweet Cream Cold Brew. They made it perfect and even spelled my name right. This location was very clean and people seemed to social distance. Seating is limited so just keep that in mind if you have a group.

1 of 5 STARBUCKS in Diamond Bar. They're all well mannered and very pleasant. There are times when they are overwhelmed and understaffed, so please be patient and kind to your batista. They do try their best.
