    6/27/26 Flavor Theory Upland, CA... Came here again yesterday with a small group of friends. The place was very clean, simple, and inviting. Isabel gave us great service! Instead of getting a bowl this time, I ended up getting a smoothie! I had the Peanut butter Cocoa blast smoothie which I've had a couple times before! Love the flavor of this one so much! Our group was able to hang out here for a while which was really nice. The music was nice, mellow, relaxing, and not vulgar. I was glad that my friend Nat was able to make it here! Such a great small group we had! It was nice seeing Ray M and Lauren M. A couple of friends I can always count on were there too! In the future I wish this business does well. It is near Vons supermarket and right next to Upland Pizza Co which should bring each other business! On future visit I will try a different smoothie!

    I love açaí bowls. Travis and I have been to this location before when it was a boba tea shop but noticed Flavor Theory was opening in May 2026. We haven't had time to check it out until now. They have 3 bowl sizes 1) Small 10 oz $10.50 2) Medium 16 oz $12.50 and 3) Large 24 oz $14.50. I usually pay between $12-$14 for my usual açaí bowls so the prices were reasonable to me. We both opted for a medium bowl and we could pick up to 3 bases. I got açaí, passion fruit and tropical, with taro chia, banana, strawberries, blueberries, pumpkin seeds, almonds, cranberries, almond butter and Nutella. Service was friendly. They have seating indoors but we decided to sit outside since the weather was so nice. Travis really liked his bowl and I thought everything in mine tasted great. I had Travis taste the passion fruit base but it was too tart for him.

    Stopped in for another visit here with a group of friends. Wanted a acai bowl but decided to try their taro matcha monster smoothie with my choice of oat milk. Delicious! It is on the sweet side but delicious! If ur not in the mood for an acai bowl, try one of their smoothies! Friendly Staff and great service from Isabel that works there!

    BOGO ad

    Saw an ad on Instagram for buy one get one free bowls (as seen on the screenshot I've attached) so my husband and I decided to try Flavor Theory. The fruit is fresh and the bowls were delicious! The bases and fruits were plenty sweet so we didn't need any honey/other sweeteners. However, I was disappointed to find that in store the offer is actually buy one get one half off. My husband only found out once he paid and assumed it was because he misread it but the ad says otherwise. We wouldn't have splurged on large bowls if we had known

    I just found the CUTEST new açai spot in Upland located on the corner of Foothill & Euclid in the Vons shopping center!! The vibes in here are EVERYTHING Super clean, spacious, aesthetically pleasing, and they have both indoor + outdoor seating Literally the perfect little spot for a quick photo moment I tried two bowls. One with tropical + guava and another with coconut + guava and OMG... both were SO fresh and flavorful!! You can truly taste every ingredient AND let's talk about the unlimited toppings YES unlimited!! Almost everything is dairy-free + vegan too which I absolutely love Amazing customer service, yummy food, great atmosphere, and overall such a cute spot to hang out Definitely recommend everyone to come try this place ASAP!!

    On the corner of foothill and Euclid in the Vons shopping center is a neat little smoothie place the staff is nice, the place is clean, has tables and chairs and cute little photo spot, the tunes are playing we got a peanut cc blast and a Taro you get to choice your milk that you would like. They look good, tasted good, they where just a little runny for me(likely watery). Next time we will try the bowls until than let's see you smoothie pics

    DID SOMEONE SAY UNLIMITED TOPPINGS??! as an broke college student in LA, i'm SICK of paying extra for anything. why are we charging an extra two dollars per topping at other açai places? Flavor Theory is pure GOLD!! I literally put three extra scoops of granola and as many freaking berries as I wanted until my ball became a mountain falling apart, and the staff were so sweet and accommodating through it all. shout out to the owner and the girl serving me, Ren! she stacked my bowl to the brim and put so much care into decorating. like look at those beautiful Nutella swirls... best of all the fruit was so incredibly fresh and I've never seen such a selection of unique toppings in my life. They have they even have rose chia seeds?? goji berries... MULBERRIES??? This is a fitness fiber maxxer's DREAM. The bases themselves were delicious and sweet. I'm such a big fan of the Taro and coconut, plus the tropical base blended flavors of pineapple, mango and coconut in like this bluish mixture that i'm gonna assume is... natural? congrats on this place for their soft opening, and i know they're gonna treat every customer from here with love! the Riverside location has rave reviews, SO PLEEEEASE CHECK EM' OUT!!

    i enjoyed this place. even though i didn't order anything from here, the menu was huge. the worker was really sweet, and she worked efficiently. she told us all the flavors of açaí that they had available. the inside of this juice bar was very modern. they had a couch, and many chairs and tables for people to sit on. overall, i would recommend this place for a cool refreshing treat on a hot, summer day.

    Flavor//Taste: 4/5 Customer Services: Mixed Feelings 3/5 Price: $ It's only $14.50 for a large which is 4 bases which is amazing. There are so many flavor options. I got a medium with tropical and coconut. I tasted the taro and its is such a good strong taro flavor. My friend got the açaí flavor and enjoyed it until she bit down on something hard that hurt her tooth. She pulled out a piece of plastic. It was the size of like half a nickel. A piece of plastic that was mixed in with the açaí. When we told the customer service worker she was like, "oh that doesn't look like the packaging, maybe it's some the manufacturer". That was it, not necessarily apologetic, or offered anything else. She was great making the bowls. The shop is cute and aesthetically pleasing. I went to use the bathroom and the lights barely turn on, looks like half the bulb is out so practically had to use in the dark. Soap dispenser delayed due to the darkness. Overall flavor and options are good, the chia pudding is a little liquidy compared to other chia puddings I've had.

    Small build your own açaí bowl

    Found this new açaí spot and had the most yummy bowl! Fresh fruit and friendly service here too

    SuperFood Bowl (Medium)

    Upon entering the establishment it was decorsted cutely and a cart held lots of board games for guedts to use. The atmosphere had a friendly vibe but the decoration was also sort of empty at the same time. The service was nice as the one staff during the visit was patient. The acai bowls were delicious and very customizable with lots of variety to choose from. We got two mediums and two large purchased with a buy one get one free coupon for the first month of opening. I wouldn't get this many bowls if I come again due to the price and probably just share one. Overall it was a good experience and I would come back because of the unique flavors and matcha options.

    Açaí, rose pudding, strawberries, blueberries, kiwi with a honey glazed topping.

    I was in the area and saw this place! ITS DELICIOUS!! The owner, drew, was in and he was so nice and friendly. He helped me decide what to get aha. This place is so clean, open space and friendly. I love all the toppings options and they are unlimited toppings! My kids even loved it!! I'll definitely be coming back soon!

    Acaí bowl: tropical and mange base with strawberries, blueberries, almonds coconut, Nutella drizzle, and cinnamon powder
    Izabel H.

    So good!!! Everything tastes so fresh and delicious, and the selection and variety of flavors for the base and toppings are amazing. Did I mention unlimited toppings, where else can you find that around here. The owner of the shop is also so very nice and I'm so happy to see a new small business grow. If you ever want acaí bowls come to Flavor Theory in Upland and have the chance to taste something so good and support a local small business.

    See all
