What People Are Saying
from Google & Yelp"Spacious venue -- the old post office repurposed into a coffee shop / cafe. The food was good, but I think the real attraction is the retro nostalgic setting and atmosphere...comfortable and airy. I'm not a coffee drinker so I can't comment about that."
"I have been coming here for years. It’s one of my favorite coffee shops in the area! There are so many things that make Post Commons special. The spacious interior that is perfect for working or catching up with friends, the delicious coffee and food (I love the breakfast burritos), the comfy couches and seemingly unlimited seating, and friendly service make this one of my go-to cafes."
"Post Commons is amazing! The atmosphere is unique & comforting. Food is delicious & comforting. & the workers are just as comforting as the vibes & food lol. A staple spot to go to whether you’re an Altonian or just passing by, it is a MUST!!"
"This is a great place for brunch! The atmosphere is great, and they have a separate room if you want to rent it for events. This is in an old post office, which adds to the charm! The service was great, but remember you bus your own table. I would definitely be going back for some more brunch!"
"There is no other place like Post Commons. You get a unique cafe experience that offers delicious food, yummy drinks, and occasional live music and events. It's truly one of a kind, and you're in an old, historic post office?! It's so cool. And you get a great view of the river. Love Post! Highly recommend."
"Food & coffee are worth going for, environment is calming and friendly, the service is unlike any around!"
