If you didn't already know, Post Commons has added two tenants to the building. They now share this grand old post office with, Good News Brewing Company and CJ's Juicery. However, this review is about them, so let me focus on them only. If you go to Post Commons, you gotta get a biscuit. Their biscuits are homemade and they are delicious. My personal favorite biscuit sandwich is the Sausage. In addition to the sausage patty, it has cream cheese and pepper jam. The pepper jam is what really makes this sammie special. If you're wanting a more hearty breakfast, you can create your own plate with items from the A La Carte menu. I've created one with two scrambled eggs, bacon and breakfast potatoes. The potatoes are cut into little cubes and fried to a crispy golden color. It's a great plac

This was a great place, lots of food options with vegan and vegetarian options, a juice bar, boba, coffee. They have a nice play area for kids downstairs which was cool. The whole atmosphere was cool. The restairant is inside an old post office building.

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.

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!!

★★★★★ 5.0 Midori Grabowski · Aug 2025

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.
