Thank you to Raymond G and Joel S. for organizing a small get-together of awesome Yelp friends over Açaí Bowls at a new business in the area. In addition to Raymond G and Joel S., Raymond's buddy, my daughter, Lauren M., and I joined RoseMary F., Jennifer W., and Jennifer's husband to chat about upcoming Yelp events and try out the new flavors this shop offers. We had a GREAT and relaxing time. The shop itself offers guests a relaxed and inviting atmosphere with comfortable sofas and chairs, music softly playing in the background, and a very clean, shiny, and well-organized setting. The bowls were prepared by a very friendly, hardworking, and welcoming employee I personally ordered a mango, coconut, and guava açaí bowl with fresh strawberries, blueberries, banana, granola, coconut flakes, and a peanut butter drizzle. My bowl was DELICIOUS, and every single ingredient was fresh and filling. I truly enjoyed every single spoonful of all that goodness. I will DEFINITELY return soon to try other flavors and toppings. read more

I came by with a foodie group, organized by Joel S., we ordered Acai bowls and smoothies on a Saturday morning. There are plenty of options to choose from. I thoroughly enjoyed the Acai bowl for $10.95. I chose Mango and Guava as my base, then added fruit toppings, slivered almonds, and shaved coconut. I chose banana, strawberry and blueberries from the available fruits and a honey drizzle at no additional cost. For the price, it was a good deal, very filling with all my favorite toppings. The shop is a new addition to this area. Isabel was on duty and patiently answered all my questions. She even had time to take a photo of our group. There are plenty of tables on the left-hand side, and a sofa in the corner that seats about 6 people. There are areas to sit outdoors, plenty of free parking, a market, pizza place, and gas station in this shopping center. If you're looking for a comfortable and casual spot to hang out, drop by when you're in the area. Sincerely, Rosemary read more

6/27/26 Great for dessert, healthy choices & hanging out type of place. They serve smoothies, açai bowls, juices with lots of toppings and bases. Isabel, the young lady at the counter was friendly & helpful. I was able to try samples of the bases for my Acai bowl. I opted for witthe coconut & mango. The vanilla chia seed pudding was next, then 3 types of granola (chose the hemp hearts & mixed granola) toppings included strawberries, blueberries & kiwi. For syrup I opted for almond butter drizzle. For a small size, it was a heapingful. It's a fairly newly opened shop, clean, modern with indoor & outdoor seating. I liked my açaí bowl, it was healthy & delicious (love that it's dairy free!) yet when I compare the flavors with Acai Mood, I find that I prefer the GIRASOL mix of the latter. It was a good experience and will likely return if in the area. This shop is located in the plaza where Vons is and the parking is shared with other businesses. read more

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! read more

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. read more

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 read more

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!! read more

Flavor Theory is such a great addition to Upland! I stopped by to build my own açaí bowl, and everything tasted incredibly fresh. I went with an açaí and tropical base, then loaded it up with taro pudding, bananas, strawberries, coconut flakes, Nutella, and peanut butter. It was the perfect combination--refreshing, filling, and packed with flavor. I also tried one of their smoothies, and it was just as good. You can tell they use quality ingredients, and I love that you can customize everything exactly how you like it. The shop is clean, the staff is friendly, and the prices are very reasonable for the portions you get. Whether you're looking for a healthy breakfast, post-workout snack, or something to cool off on a hot day, Flavor Theory is definitely worth checking out. I'll definitely be back! read more

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. read more

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. read more

Terrific! I had pretty basic açaí bowl, ordered it just before closing and it was still completely fresh and well crafted. I took it home, popped a THC edible and let me just say...Heaven. Eating this while high off a medical dose of the devils lettuce was practically a religious experience and reminded me of my stoner years in the 70s. I will be back for more. Service was also very kind. Thanks read more

Got two smoothies, do not really recommend due to the bad service and cost. Two very small smoothies costed $15. The lady taking our order was very awkward, unhygienic, and rude. The chocolate coco blast was okay and the fruit based ones (strawberry, banana) are bland. read more

Went on Saturday to the upland location of flavor theory and omggg it's so amazing. First off, the guava base is my favourite. They let me and my sister sample as much as we wanted. Second, the unlimited toppings is so refreshing, and everything was very fresh. The place is very nice on the inside too, very clean. Last, service was great and everything overall was amazing. I RECOMMEND!! read more

Everything was great, employee nice and friendly and patient. However, owners need to get more help. I waited like 20-30 minutes to get a bowl.
