KOIO TEA SHOPPE (Diamond Bar)

My favorite is the sweet potato milk tea! Very creamy and you can taste the purple yam.

Tasty brown sugar milk tea with boba!

I came on a Thursday around 5:10 pm. No one was in line when I arrived, only one other customer was waiting for his drink.

I stared at the menu for 5 minutes until a staff member acknowledged me and came out. Maybe I was too quiet so they didn't notice me... Anyway, I ordered their brown sugar milk tea with boba, 50% sweetness because lately every drink I have been ordering is too sweet. I used to think I had the biggest sweet tooth in the world, but maybe not anymore. Okay back to the review... even though I adjusted the drink to 50% sweetness, it tasted like 100% sweetness! Maybe my taste buds are out of wack. Who knows... but I have drank A LOT of boba all my life... I am literally boba obsessed and usually get regular 100% sweetness! Anyway, I used their 10% off YELP check-in coupon, and then tipped them 20% my total even though I waited some time to order and my drink ended up being too sweet?... Not sure why I did at the time, I must have been feeling generous because I'm pretty broke right now

As far as the drink, it was good! I enjoyed it! Just -1 because of the lack of acknowledgement when I arrived/no staff member coming out to take my order until 5 minutes later (with NO ONE in line before me)... and the fact that while the drink was tasty the adjusted 50% sweetness tasted like regular 100% sweetness... and there are other boba shops in the area that I enjoy more. That said, I would still go back and order this again! Maybe 25% sweetness next time...

Other random tidbits:
-the prices are $$ but I knew that going in
-parking lot area is huge, you will not have any problem whatsoever finding parking
-inside the actual shop is cute!
-when checking out their online website, I noticed that if you sign up with your email, you can get 25% off on all orders

unique menu items, good drinks! my friend got the sweet potato/taro oolong milk tea w boba & liked it! really pretty drink

Online order was very easy and fast. No need to sign up for anything. My drink was ready in 6 minutes. I really like their cheese foam.
