Such a cool space in the old Post Office. Elevated coffee house vibe with total respect and love for the building's history. So Alton! HANNAH is the GM and she is an amazing host. Knowledge and willing to share ingredients and labels as she helped me order Gluten/Dairy/Sugar free. We had yummy greens with eggs and turkey sausage (hold the croutons). The poppyseed vinaigrette was dairy free and just perfect. My matcha latte and Clyde's coffee latte were delicious. Troy had pizza and he loved the crust ( he had regular but they DO offer GF crust AND vegan cheese!). Sam's French Toast looked amazing in all its gluten-filled glory. We also tried the immunity shots from CJ's Juicery and they were dynamite. If we still lived here full time I'd be making the drive over from STL once a week for that breakfast salad and matcha. The menu is varied and thoughtful, altho I would love to see them find a way to offer at least one gluten free bread (I bet their avocado toast rocks!). I understand it is not an easy undertaking for small kitchens to manage proper handling of GF if it's not their focus. However I promise those on a restricted diet can absolutely find something here due to Hannah's expertise. read more

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 place to meet friends for a cup of coffee. The staff is cordial and makes you feel welcomed. Why go to a chain coffee shop, when you have a unique one in a old post office building? There is, no reason to go. When: February 4, 2026 Why: Biscuit Sandwich read more

The food is generally good - I recommend the Post Toast. The coffee is pretty great and if you are around for a seasonal Spookster latte or Butterscotch latte, get one. Service is good, although when there is turnover, there can be challenges. I used to love the ambiance of this place - beautiful sweeping views, mismatched old furniture, and just really comfortable in a shabby chic way. However, young families discovered it and made it their own and now, it's an awful environment on weekends unless you love a plethora of shrieking kids in an environment that echoes sound. read more

I live in Edwardsville, but a couple of former coworkers raved about this place. I was in the area, so I decided to put in a couple of hours of work at Post Commons. What a neat place! And it's huge! They even have a rental space in the back! Finding an outlet to sit next to was a bit tricky; I think it would be beneficial to designate an area specifically for laptop users. I enjoyed a lunch of Post Toast with a sunny-side-up egg and a lavendar mocha. The toast was amazing, but I wasn't a fan of their lavender. I'm excited to go back and try something else, though. read more

This place is amazing! I finally made it over to Alton to check it out. I live in St. Louis city so it's a trek for me. It's a huge place with plenty of seating. They even have a private room you can rent out in the back. There was a bridal shower going on while I was there. So cute! I love the fact that it's an old post office. It's so unique. The coffee was spectacular. I got the white rose latte which was on special for February. Delicious! I also grabbed a pastry which was so so yummy. And then I had the slinger as my meal. It had a little spice to it, but it was delicious! I would definitely get it again. I can't wait to come back to this place! So many cute places for photos as well! Keep in mind parking can be a little tough if it's busy. It's street parking. There is not a parking lot. Also, there is not table service. You order at the counter and they give you a number and then the food or drinks will be delivered to your table. We went on a busy Saturday morning And the line to get pretty long. But it's so worth it! We had to wait in like about 10 mins to order. Then about another 20 for our food and coffee to come out. read more

This place is so cute!! So many vegetarian options and the French toast was fantastic. I also got the matcha with lavender and it was divine.

Always good food and a relaxed atmosphere. I love how they took an old post office and made it into a coffee and breakfast place. They are helpful at the counter and their food and drinks are delicious. We will be back. read more

I did not realize I hadn't written a review for Post Commons yet! I have come here several times over the past few years and really enjoyed it! The location is unique as it is an old post office building that maintains the integrity of the buildings design (inside and out!) the service is always friendly and helpful. Our orders are made efficiently and with care! Usually my fiancé and I have had their coffee/tea items but a while back during a visit we got breakfast and it was lovely! I currently live outside of MO/IL for school, but am looking forward to coming back soon once I move back! read more

I'll have to go back a few more times to really get the feel of it but inside the building has tons of potential and they are doing a great job so far with the aesthetics. There are different sitting areas so I don't know how quite it is or isn't in different sitting spots. It was a little noisy due to little ones in the area where I was but that's what kids do lol. There was quite a bit of building materials and other things sitting around but it wouldn't stop me from going there again. Upon walking in it was a little different because you don't really know where to go until you start to look around and that's because the building is rather large. I ordered the lavender tea and wow, I think I have a new favorite! I will definitely revisit on another day and try more of the menu out. read more

Post Commons - Lavender fog tea minus the lavender - Breakfast & Brunch Near Me - Alton, Illinois

Old post office conversion was very cool. Stopped by for a quick pick me up, loved the live music on Saturday morning & the fact that the lattes still taste like coffee and not just syrup! I myself got a lavender fog and it was delightful! Service was quick and friendly, they were celebrating an anniversary so we drew for a reward and received $5 off! We will definitely be back for breakfast next time we're in the area! read more

Post Commons - Live acoustic music, perfect Saturday morning vibe - Breakfast & Brunch Near Me - Alton, Illinois

Celebrated a wedding here this past weekend. If this place isn't a consideration for any couples it should be! Just from my experience as a helper to the party, staff couldn't have be more friendly and accommodating to things we needed. They were extremely hard workers who provided amazing service to guests. And old post office turned event venue, you can still see the old post office come to life. (The mail boxes turned wine holder!!??" very clean and quaint and plenty of space to make it to your needs Opened M-S 7a-2p you can also pop over for a breakfast and coffee! (*note I did not eat here was just here for an event) Highly recommend a pop in if you're in the Alton area not just for a treat but to enjoy the history restoration as well! read more

love the breakfasts here, and the coffees and teas are always spot on. The building is adorable as well.

Very charming cafe that offers a diverse selection of teas, coffees, pastries, and sandwiches. I opted for the Avocado Sammie & seasonal peppermint mocha. Both were beautifully crafted, filling, and delicious. The interior of the cafe really captures the essence of the old post office and has a very welcoming space for working solo or dining with friends. I totally recommend. read more

This place is a hidden gem.

Great place for business meetings . Nice breakfast and coffee and happening vibe. Also enjoyed the whole bean bagged coffee.

Food hit the spot! The burrito was flavorful and has everything you could want inside with a nice hint of spice in the salsa. The biscuits from the slinger were soft and balanced well with the gravy. We got the Fall Spice Latte and Dirty Chai, which helped get us in the fall mood. This space is gorgeous! We definitely understood why so many have events here and it so fun with all the antiques and pieced together finds. Super cool that they were able to convert the space and do so much good with it. Service was timely and friendly. People helped clear our table and so we weren't waiting, we got our coffee first. The wait time for the food wasn't too long by any means. Lastly, we had the best cashier, thanks Grace! read more

My favorite place to remote work when I'm home. With each passing year, I've only seen the atmosphere get better and better. I only wish they were open past 2pm like the other coffee shops in the area. Maevas is open til 7pm and Germania is open until 5pm. If it were open til 7, it would easily be 5 stars. read more

Amazing local coffee shop with good eats. The building is the old Alton post office. It's perched on a hill downtown with beautiful views of the river outside. The atmosphere is great, service is always solid. If you're in Alton and like coffee this is a must stop. Their lattes are incredible. Go for the view, the atmosphere, the drinks and the food! read more

The Post Commons is a great establishment serving breakfast and lunch. Coffee is their main drink but if the day calls for it-the hot chocolate is fantastic!!! We used PC as the venue for our daughter's wedding this July, 2025. The venue is wonderful and has incredible ambiance when set up. The staff is so helpful and they go out of their way to see to it you have everything you could want! As a venue or a for cup of coffee (hot chocolate) the Post Commons is the place to go! read more

Historically an epic Post Office from another era, one of the coolest buildings in Alton serving fair trade coffee and breakfast bites. The vibe creates a great place to hang with friends or your laptop. Cool Alton artwork and history on the walls. Worth a visit just to see inside. Coffee is roasted in house. Pastries and breakfast bites. Friendly staff. They only serve alcohol at private events. An amazing venue for weddings/parties/events. With a bar and a band, a party here would be one that guests would never forget. For every day coffee and hanging, who needs a Starbucks when you've got Post Commons? read more

I was checking out Alton because a co-worker recommended visiting the nearby state park. However, since I started my day super late, it was getting darker when I arrived in Alton. So I ended up checking out this coffee shop instead, and boy, I was so surprised at how huge this place was. I guess this shop was a post office back in the day, so the interior is spacious. I think I also saw that it can be an event venue. I'm unsure, but you can rent this event space... Let me tell you that other than how spacious and huge this place is, they have two open bars- one for coffee and the other for drinks--what a clever way. I ordered a butterscotch latte with chai scone for a snack. The latte was so delicious, with its strong taste, butterscotch, and espresso taste. The chai scone was perfectly baked, and you can taste the chai flavor perfectly. This whole coffee shop is such a vibe. I liked it a lot, and I highly recommend this shop if you're ever in Alton, IL! read more

Highly recommend. Really interesting building/space. Really like the vibe of it. The kids play area was such a nice surprise. The coffee was great. We ordered the pork sandwich, slinger, and French toast. The slinger biscuits and gravy had great flavor. The French toast was amazing. Didn't get a chance to try the pork sandwich but my son enjoyed it! The people were really friendly too! read more

This place was converted from a post office to a coffee / breakfast spot. They also host weddings. This place has super cute vibes. Food was fresh, came out quickly.

Stopped at Post Commons for brunch and had their Biscuits and Gravy. My wife had a blueberry muffin. I love this place! The service was patient and friendly and the food was amazing. I consider myself a biscuits and gravy guy and their version was both different (unique?) and delicious. We loved the atmosphere and decor as well. Look forward to returning! read more

Yummy food and coffee!! The breakfast burrito Pony Express is beautiful and delicious! The gentle giant Sammy was so yummy on a fresh house made biscuit. The pepper jam was the perfect sweet to salty touch. The kids for the French toast with bacon and they loved it. I had the seasonal latte. Blackberry & lavender. It was beautiful but a bit tart for my preferences. The wait time to get the food was long so that was the only downside we experienced. The building is beautiful! We will be back read more

The Post is unique among coffee shops, and I have a lot of great memories here. In addition to their pretty good coffee, they have some of the most inventive brunch foods I've ever had. The menu rotates, so if you have something you love, be sure to enjoy it a few times before it's swapped for something new! While it can be a bummer to lose favorites, it also means you get to try amazing new creations each season. The space is big and roomy with lots of tables/couches/desks, so you're sure to find seating whether you're there to work, read, hang out with friends, or just grab some some food. read more

Post Commons - Iced mocha - Breakfast & Brunch Near Me - Alton, Illinois

Very cute coffee shop in Alton, IL. Converted from an old post office, there decor is super rustic while creating a minimalist / modern feel. Visiting on a Thursday morning, the place was pretty empty with lots of seating available. There was a nice breeze outside so we took advantage of the outdoor patio area. This place is located on top of the hill, which gives you a nice view of the Mississippi River. I ordered a breakfast burrito, which was really unique with the kimchi and a sticky rice. They have tofu and pork as options for the inside of the burrito to accompany the scrambled eggs. I opted for the pork and it was fried to be a little bit on the crispy side. I wish I had more of it, but the flavor was on point. I ordered the Americano and it reminded me more of drip coffee. Maybe they watered it down too much. I think there may be only a single shot of espresso in here so the ratio is way off with around 12 oz of water. I'd come back for the burrito but not for the coffee, at least not the americano. read more

I enjoy my brunch at Post Commons. It is situated at a really unique old post office. For COVID, we sit outside. The waitresses deliver food and drinks to our table. Yet, the service still remain outstanding. We ordered Green Giant, with $1 additional to add avacado and fried green tomato. I also got a Jade Cloud tea. All tastes good. Totally enjoy our visit. We will certainly be back. read more

My background is event planning (wedding, corporate, private). Over the past couple of years, I have been to Post Commons a few times and was not at all impressed. I wanted to book 2 other events this year and next but waited to see how the special event went a few months ago went...and did not consider Post Commons for the reasons below. Regarding the special event a few months ago, the flooring was a big trip hazard. The windows & shades are in great disrepair, broken, unsightly, filthy, and in no way match each other in about any way. The plants are very poorly cared for with dead leaves (ok for my home, but not for a business). The dust and grime on the windowsills and molding was gross...and had been there for a long time. It's like going into a cheap old church basement for an event...but more costly, and touted at better quality, but not. Parking is not logical over by the Stratford is NOT convenient. Disabled entry is a joke. The Third Street hill is horrible to utilize for a special event. And, if a special event occurs while church is in service, there is zero parking. The staff for the special occasion (not sure of the staff turnover) was not helpful...even a little. The event coordinator or any staff, period, never-ever responded to phone calls, emails, text messages, etc about booking the 3 different types of events (I contacted them at separate times), needs for the events, and more. We had to go 'in person' to get someone's attention...and Post Commons is not that busy! During the event the staff seemed put-off to be bothered with a question. The day of the special event the staff arrived late to unlock the doors, making set-up late. The ceilings are high so that it is a challenge for the AC...but it is a challenge that should be met to keep larger groups comfortable. While it was not hot outside, inside it was very warm, especially since everyone was dressed up. Love the building...but I would never ever hold another event at Post Commons and will never ever again meet anyone there for coffee. Ever. As an event planner for many years, I have booked hundreds of events with very high and very low budgets, and Post Commons is in the bottom 3 on quality of service and quality of venue in the entire St. Louis/Madison County area. With several other venues to choose from, I recommend choosing another, even at a higher price. read more

Love this place. The food and service was awesome. Our family really enjoyed this unique setup.

Ambiance was so cute! I got the breakfast sandwich and it was delicious. Perfect study or hangout spot

A really fun place that I wish had longer hours. This historic site used to be an old school post office, and it shows. You can enjoy the infrastructure and artifacts of a different time while you are there. Post Commons has many of the features that make an exellent cafe: several types of areas for various social needs, unapologetally distinct decor, food options, and sound panelling. (Seriously, when will big cities understand the importance of acoustics in a shared space)???? They even steeped my tea at the correct temperature, something even excellent cafes often overlook. My complaint: the food is trying to hard to be fancy. No one needs flower petals on their avocado toast. If it's fresh, hot and tasty, that's good enough. Their coffee could also stand to be a little hotter, but that's a matter of taste. read more
