The Coffee Bean & Tea Leaf

Good parking, although I arrived near closing time when that could be expected. Wanted and got a whole bean medium roast 16oz. valved bag of Mocha Java dated 29 May 2019. That's a very "long" date in the internet's geek opinions--they want a bag just a day or two old. I took it home and ground enough for two very good cups finding that it had held up well, likely because of the valved bag. The attendant was very pleasant too and I was in and out in under five minutes.

Previous to covid this was a great place to get your laptop or mobile device out and work while drinking coffee or a latte. Lots of electrical plus along the bench to charge devices . Only complaint is the service is a little slow. Mostly a local residential crowd. Diamond Bar is a bedroom community. Most residents are in the financial or real estate industry.

I went on Saturday afternoon they have going on the deal but one get one free it was a good experience the staff was friendly and the drinks was ok to sweet for my taste and less coffee but next time a just ask for a extra shot of expresó

It’s only 2 persons working on this location so prepare to be waiting but overall it’s a good place

Don't get the hot drinks here. The cups they use is extremely low quality, it leaks on the bottom.

Iced drinks are good.

Drinks are good, prices are about the same as starbucks. One star because the customer service via drive thru was horrible, waited 11 minutes in line once i got to the window i was told they were short staffed and was told to give my info so the manager ( Jonathan) would call me back to receive some sort of coupon....never got that call. First and last time i give them my money.

Sorry guys, I can only give two stars because the facility is very nice. With that being said, why would you be cleaning the windows at 7:15pm and asking people to move? So unprofessional! In addition, they were out of whipped cream! Wow, welcome to the neighborhood Coffee Bean!!! I think I’ll stick to Starbucks, their reward program is better anyways!

It's SO nice to have a drive thru coffee/tea place this end of Diamond Bar! Great location, good service, good variety in the menu itemsand really good hours (open early, closes late). I LOVE that they have flavored unsweetened herbal iced tea! And more than just chamomile and mint like everywhere else! Their tea lattes are delish, dark hot chocolate is tasty and not so sweet, and prices are competitive. My hubby likes trying all their different coffee drinks too. They have a number of small tables inside, usually with people working/studying on them and a nice patio to Lounge or get work done too. I wish they had some protein drinks with low sugar and maybe some higher protein food options but overall I love this place and am so happy they are at this end of town! Right next to Chipotle is very convenient too :)

Went in March 8th around 8pm. Ordered a large iced coconut caramel latte with extra caramel and soy and an iced water. They were so sweet, so understanding, and generous. The cashier said he was new but he did a great job and was extremely kind. Thank you! Drink was great!

Cheaper than Starbucks. But less choices

Way better than Starbucks
