Staff was incredible. There was a mixup with the order and they were so kind and gave us a smoothie for free. The smoothies was delicious and the chicken empanada was perfectly cooked. I will definitely come back again! Best smoothie place! read more

Jamba was a decent stop for a quick snack and smoothie. I tried one of the newer food items, the chicken empanada, and it was okay... convenient but nothing particularly memorable. I also got my usual PBJ smoothie, which was solid and consistent like always. Overall, a perfectly fine quick-service option when you want something easy and familiar. read more

First time I went to Jamba and only ordered food. I walk in and the employee was making bowls for the customers ahead of me, but she still managed to greet me. Once it's my turn, I tell her I'm there for my mobile order and she starts to prepare it. Thats fine, because I was wanting it hot when I picked it up, especially since I ordered mozzarella bites. The bites are a NO for me and the empanada had an "ok" tasting filling, but the crust, wasn't flaky, wasn't crunchy and had no flavor. It just tasted like a flour crust....no flavor at all! It was just something to hold the filling in. They tried it, but it wasn't my thing. read more

Today was soo hot outside and yea its summer but I wanted to get something refreshing on my lunch break. I thought I'd come get a white gummy because I love them. The manager asked me if I was enjoying my drink and that if there was anything let me know. I really appreciate that from the owner...he was not to busy to think about the customers! Thank you for my drink and I will definitely be back again and again!! read more

Had a great experience at Jamba Juice! Jesus and Fatima provided amazing customer service. They were both so friendly, patient, and genuinely helpful with recommendations. You can tell they really care about making sure customers leave happy. My order was made quickly and came out perfect. Their positive energy made the whole visit even better. I'll be coming back! read more

Jamba - White gummy - Juice Bars & Smoothies Near Me - Fontana, California

The drinks and food are always amazing, and I've never had an issue with the quality or the employees themselves. My only concern is that the staff is often in the back, which I completely understand since they're probably working. However, there are times I've waited up to five minutes or longer just for someone to come out to the front. Maybe adding a doorbell or some type of alert would help let employees know when customers are waiting. 3 starts because the wait. read more

Jamba - Never any employees - Juice Bars & Smoothies Near Me - Fontana, California

The smoothie selection is strong: Items like the mango-a-go-go,strawberries wild and the açaí bowls get frequent mentions as hit choices. For those wanting a quick healthy (or at least healthier) treat, this Jamba location gives a convenient option in Fontana--a smoothie or bowl works well for on-the-go. Açaí bowls and oats toppings (strawberries, granola) are available and appeal to those looking for something more substantial. This Jamba Juice location in Fontana is a good casual stop when you want a smoothie or bowl and are okay with a bit of variability in service and execution. It hits the basic desire for a refreshing snack/meal alternative to burgers or fast food. Erika was one of the employees and she was super cool and friendly. Made the experience even better. read more

Had a good experience at Jamba Juice the other day with Jesus, he made my drink perfectly and even upgraded me.

Rude employee at the register, didn't know probably how to great a customer No washing of hands after handling money. And the drink was watery, wasn't made right read more

Perfect treat on a scorching hot day! Cashier helped us adjust our menu selections to Small sizes (small not listed for some items) which we appreciated because I didn't want my kid drinking a Medium all on his own just because he was choosing a special seasonal flavor. (2/5) Kids' blueberry strawberry blast - tasted a tad sour and healthiest out of the 4 smoothies we had. I would only get this for health reasons for kids and not for taste if I had to... (5/5) White gummy bear (from their secret menu) - was so good! Probably the least healthiest considering it contains three different scoops of sherbet but I loved it! (4/5) Orange dream machine - classic orange creamsicle flavor (4/5) Seasonal classic watermelon - nice natural flavor! read more

Jamba Juice never disappoints! The smoothies are always fresh, delicious, and perfectly blended. The staff is friendly, and the vibe is super positive -- my go-to spot for a quick, healthy treat! read more

Order fresh juices Received full cup of ice with few drops of syrup juice with one teaspoon of rotten fruit as a topping Please don't advertise this as a fresh fruit juice Fresh fruit juices contain actual fruit not sugary syrup Was my first and last time to buy their so called fresh fruit juice, not recommended. read more

This has to be the worst Jamba in CA. Every time I come they're out of something and it always smells like the new guy is burning the bread.

Under staffed. Came to this location during lunch time and there was only one person working. Asked for an impossible handwork and it was given to me really sloppy. (Photo included). There was only one other customer when I arrived. Arrived 12:15 order was ready by 12:40. Employee didn't greet us until customers who arrived after us were addressed. We only had two drinks, a parfait, and the handwich. Overall I would not return to this location. Customer service sucked and it took forever to get out of there. read more

No juice once again. Glad to know this location censors reviews. Left a review a few months ago critiquing their service and their lack of juice but it is nowhere to be seen. I have been to this location several times before (hours before closing time) but every single time they don't have the fruit to make it?? Stop wasting your time coming here like I did. Terrible service and false marketing. read more

I had an issue with my order upon arrival and was shocked at the lack of response. I was told to just pick something else. The lack of customer service as a whole leaves me choosing to not return. read more

I love Jamba Juice but I just left because it's 8:23 and they still weren't open even though the hours are 8am-8pm. I got there at 7:50 to get subway and then be there when they open and start my day but they never showed so I left. read more

The smoothie was pretty good and decent price. I had the PB Passion and they had all my preferences, Almond milk, vegan protein. The services was good and quick. I recommend. read more

This location never has any of the ingredient to make your drink. I've come on several occasions wait in line get to the counter and tell me oh I'm sorry we don't have oranges or we don't have carrots... waste of time and effort going here... read more

Disappointed. I usually love coming to this location because I hate making my own smoothies and the Jamba on Sierra never tastes too fresh. I guess I better dust off my own blender though. Today's visit was a quick lunchbreak run for me and a few others. I was in and out in about 5 minutes, a bit of a rush so I didn't check my drinks before leaving. I should've. They were poorly mixed and mostly juice. Little to no sherbet and they kept leaking because there was no slush to the "smoothies". To add to it, there were powder clumps in two of the smoothies. No one finished their drinks and I feel like it was a waste of money and time. read more

I typically receive pleasant service at this location UNTIL today. I was greeted by a girl and she told me she'd be right with me. Instead, Tyler helps us out. My younger sister first ordered a MEDIUM white gummy and substituted pineapple sherbet for raspberry. She realized she didn't have enough money in her gift card so she asked to change it to a small. Tyler then says "Are you really gunna make me void it?" She then apologizes. He goes "It's just a hassle." Very rude. I don't know how Jamba Juice's POS system works, but it should be THAT difficult to change an order before payment. Also, he doesn't fill her cup all the way even though there was plenty of smoothie left in the blender. He proceeds to make the remark "Not-so-White Gummy" which was completely unnecessary. read more

Glad to know they turn their phone off so nobody can call. Wrong door dash order and tried to call the store.

The workers were kind and quick however my matcha was really messed up, hopefully they learn how to make it better next time. I ordered light sweetness but it was overwhelmingly sweet and could hardly taste the matcha flavor. So upset because this drink was $6 for a small :( read more

Jamba - i poured the Gotcha Matcha with Sweet Cloud Whip into a cup and realized it was 90% cold foam. - Juice Bars & Smoothies Near Me - Fontana, California

0 stars. Came to petco to drop off my dog for grooming. Jamba sounds nice and refreshing. Nope... sign says they open at 830. It's 909 and no one is here and the doors are locked. Pathetic. It's a wonder this one hasn't closed. The one on campus and the 210 shut down years ago and they had much better employees than this location. The writing is on the wall. This location won't last long. read more

I tried to give this location my business for the 3rd time. I went at 1:00 and the business was closed for a 30 min break for 1 employee. I took my business to juice it up and found, 3 employees. I got my smoothie within 2 min. Again the owner of this location in Fontana clearly doesn't like to make money. I prefer Jamba juice but when I try to go it's always closed for a break. This is the last time I go there. Go to juice it up because this location sucks. Always on a break and doesn't care about customers or making money, clearly. I'm so glad to not be this owner. I don't like giving away money or teaching the young men and women of today to lose business and that customers don't matter. Again too bad 0 isn't possible read more

11/15/2023 so if it's raining outside they close an hour and a half early? That's sum bs.

Shabby. Not worth coming back even though my smoothie was good enough. The music was too loud and the place needs some repairs or decor. Owners have to realize that their competitors are nicer. I was just driving by. I can go to several others within a 10 mile radius. read more

Jamba - What was on the wall? Doesn't take much to paint or cover with a picture. Makes the place look shabby. - Juice Bars & Smoothies Near Me - Fontana, California

Wow... Friday night, a few people but not crazy. 2 people working at a snails pace. No interaction with ordering customers or customers who have been waiting for their drinks. Store is a mess, trash all over the floor, bathroom out of order, paint peeling off the walls. Not sure when the last corporate visit was but they need to have one quick. Will not return to this location. read more

Service at this location is horrible. Walked in my children needed to use the restroom. The young lady stated that the bathroom was not working and rolled her eyes. This was today June 10 at 12:50 PM. The location smelled it smelled dirty. It smelled like a toilet, whenever I would ask the young lady any questions of the order that I was placing she would sigh and roll her eyes at me like I was an inconvenience for asking her questions, I asked her for granola on the side. My son doesn't like granola and she was offended. She was like what do you mean with a really nasty attitude she kept tapping her very long nail extensions on the counter as if it's for me to hurry up that I was wasting her time First of all when you work in the food industry you're not supposed to have nail extensions on and those were very long she kept tapping them on that damn counter they don't even take Apple Pay as a location. I will never go back to that store, I took myself and my kids to the other location which was Menchie's I bought them yogurt. The young lady at the yogurt place was super nice super helpful. The area was clean. I will never go to Jamba Juice in Fontana on sierra Lakes Parkway. I hope this gets to a supervisor and they call me back because I will be calling also corporate read more

I came in this am to grab a smoothie before work. I wanna say Karla was truly a blessing because I always want my drinks thick and I usually can never get it that way because I've been told we don't do that at other locations. But today I finally found the perfect location because she Definitely got my drink thick and also listened to my special order I truly appreciate great customer service and I will be back weekly read more

Sara was wonderful! Very welcoming. Enjoyed the ordering process, and my drink she made was the best I've ever tasted. White gummy. Recommend this location over Nectar down the street. read more

Very disorganized staff. Took 30+ minutes to receive our order. Two stars because the drinks are decent.

Best customer service in town! I ordered and the staff was so friendly with my kids and I. Bryce was a doll! He even gave my daughter a bigger cup for her medium smoothie so she could be just like her sister. I would highly recommend. read more

Always on time and fast! I normally order online and the drinks are ready on time or before!Drinks are always amazing! Love this place!

I feel bad reviewing during a pandemic, but when there's food involved something still has to be said. My fiancé placed a mobile order here, but it saved us no time at all as they just started making it at the estimated completion time when he was walking in to pick it up. When we got our smoothie bowls they were super watery, it looked like they should've gave us straws instead of spoons. So watered down that all the fruit sunk to the bottom and it wasn't even visible. Like I said.. I understand everyone is trying their best during these crazy times, but you have to at least get the order right. It wasn't a smoothie bowl, it was juice with chunks of fruit. This was what it looked like after I ate a few spoons and it was taken only about 5 minutes after picking it up. They're actual smoothies are thicker than this was. Just sharing this so that hopefully the workers will pay extra attention to what they're doing and be able to still give out good quality orders. read more
