Function Coffee Labs

Listen. I am a regular here because I live one minute away. And also my wife and I throughly enjoy vibrant. So we are happy to spend the money and also support queer business/with queer workers. As a chef in the neighborhood I pride myself on treating every service worker as human being and maybe it comes off chatty. But I gotta say. There is a worker here that is tall. Shaved head. And they are very unwelcoming to regular locals in this area. If I see them working I fully avoid you guys and rather walk to Shot Tower for better customer service.

Really amazing baked good and coffee. Only downside is locals sit for hours with laptop making finding a seat difficult. Space is small but worth a trip for a good cup of coffee.

I used to go to here at least 2-3 times a week. I thorougly enjoyed their coffee, especially the specialty latte as they never go overboard with their flavors. You can still taste the expresso, subtle added natural flavors, and there's a nice balance of the expresso:milk ratio. When i get a good cup of latte from them, it makes me very happy.
However, I've had at least 3 instances where my latte tasted like diluted milk with very faint to no taste of expresso, all made by the same barista (who seems to be making their coffee everytime I try to stop by now). I don't understand how differently the lattes were made - I could never finish them. Initially I thought it was a bad day, but it was consistently terrible the 2nd, 3rd and 4th times that I cannot justify spending $7 on a latte I dislike. If you have boiled the art of coffee making down to a science, I don't know how this can be explained.
We make our own cold brew during the week to drink at work. On the weekends FCL latte is my treat. But it's now become an anxiety trigger for me when I go to the shop and see the barista standing behind the counter. I've straight up just walked away when i see that. I don't know what to do - I don't want to be rude, but i've had amazing lattes like nowhere else made by all of their other baristas. My husband has tried politely requesting a different barista who was taking our order to make our latte but was met with resistance and attitude by the barista. For a shop that prides themself on their coffee-making technique, you should be more accommodating for your patrons.
We would like to come back for your amazing lattes. But we're put in an extremely awkward position as a paying customer. I hope you can figure out a system that is welcoming and makes it easier for your customers to enjoy their coffee. Or at least quality control and ensure consistent training for your baristas.

Absolute gem!! In a bustling city, coming across coffee shop with great service, incredible bites and even better coffee is a must! Be sure to try the cinnamon roll! You will not be disappointed!

Worth the trip! I've been wanting to try for a while, but don't live in the area. My cortado and savory danish were definitely worth the trip. Espresso was very smooth with a little bit of sweetness. And the sourdough adds a bit of a twist to the spinach and artichoke Danish. Will definitely be going back for croissants and barista specials (I regret not trying the French Toast latte, but a cortado is my standard to try at coffee shops).

Don’t eat here. Especially if you want a legit, West coast sourdough cheese danish. Or a refreshing vanilla latte that isn’t over sweetened like a cup of sugar with milk. Thanks function!

I go here every day. Espresso is done correctly. You can get pour-overs and they have specialty drinks. The most important thing, however, is that they know how to steam milk properly. Every other place in Philly makes wet cappuccinos and calls them lattes. If you are a coffee nerd this is a must go.

A lovely little space, with friendly, knowledgeable and helpful staff. My pour over is excellent (I love the science-y presentation) and my squash/goat cheese danish (eaten too joyfully to be pictured) was superb—savory, warm and flavorful.

Function is by far the best coffee place in South Philly. From the minute you walk through the doors, the experience is warm and inviting while the coffee is consistently incredible. Grab a pour over and stay a while, you won't be disappointed.

Really cute place! It's small and can get crowded easily but there's a park across the street to sit at if you just want to hang out or it's near the Italian Market which you can walk around. Got the cinnamon toast crunch latte iced and it was absolutely delightful! There were a ton of pastry options I would love to try next time like bronuts and cinnamon rolls
The staff were super friendly as well, overall a wonderful experience despite the excessive heat outside
