I usually get the loaded PB&J bowl, I’ve never been disappointed in the flavor, presentation or time it takes to fulfill the order. I usually order ahead, though it says 15 minutes for an ASAP order I’ve never waited that long. It’s always clean in this location and staff is very friendly. Only “bad thing” is there’s no street parking directly in front of the building so you have to park down half a block or in the parking garage behind the building.

I like south block. I do… however, finding plastic in your Smoothie is not ideal. You need to rinse out the blender mixing tubs better. Then I decided to rinse out the rest of smoothie in a strainer. I ended up spitting out smaller pieces. Its clearly from the bristle brush you use to clean the tub out to reuse. As you can see, the plastic is not removed before reusing on the next drink. I’ll keep the plastic pieces and drop off with Manager.

Fast efficient and friendly service! I have ordered in person and via the app for this South Block location and each time has been flawless. The order is always faster than anticipated, but there’s a cold area where they keep your order, so it doesn’t thaw. Smoothies and bowls are freshly made with super fresh ingredients. It’s very easy to customize anything (add or subtract or substitute an ingredient). Anything with peanuts has a special sticker. You don’t like what you ordered? Let them know and they’ll remake it. Staff are always really friendly! The store is colorful, clean and even has swag for sale if you’re into that kind of thing.

Great place to get a somewhat healthy acai bowl. They have several kinds, and some are healthier than others. My personal favorite is the Nutella bowl. The service is pretty good, and the atmosphere is decent. There is plenty of parking on the street and garage.

Review for South Block
Just finished my workout and stopped by South Block, where Omar made an incredible shake! He was super personable and made me feel right at home. Honestly, the best shakes I’ve ever had—truly the best on the planet. I’ll definitely be returning every day for more! Thanks, Omar!

I was born and raised in Brazil and grew up eating açaí. South block is honestly my favorite place to get some açaí bowls that somehow, reminds me of home. However, this location has consistently been disappointing. The past three times I ordered my bowl, it has come with very little Nutella (so little I can barely taste it), really small portion of strawberries and a half empty bowl. This picture I am posting in my review was taken today, my husband got his bowl right but mine, again, awful (I paid extra for Nutella this time and still very little came in.) I always order the Nutella bowl e for him, the Loaded PBJ, however mine is always wrong. To pay $14 in a bowl and still not get what they claim to give is very deceiving. Not sure I will be coming again to this location. Extremely annoyed.

It’s very clean in there and the staff is so friendly. Their smoothies and bowls are amazing and flavorful. I love how they don’t water it down with ice so you really get your money’s worth. They have amazing flavors and their seasonal options are always fun and delicious. I love this place and I’m so glad they have a location near me!

I’ve been to South Block a few times now, and it has quickly become one of my go-to spots. The almond butter smoothie bowl is delicious! The place is clean, and the staff is super friendly and welcoming. It’s in a great location, perfect for a morning treat or an afternoon hangout. If you’re health-conscious and enjoy delicious smoothie bowls, this place is worth a visit!
