Function Coffee Labs

I ordered a butter croissant and it was old and dry, and it was a sourdough croissant. I eat a lot of butter croissants and I never got a sourdough one before, it definitely shoukd have been labeled as such. Mainly my complaint is that it was stale and should have been thrown out and not sold to me.

Really great coffee, lovely interior and service. I got an iced mocha (the chocolate was made in house!) And my only suggestion would be to mix in the chocolate with the hot espresso before pouring it over the cold ice / milk because the chocolate was hard and stuck to the bottom / sides of the cup and so was not integrated into the drink well.

Great little coffee shop - breakfast sandwich was good, latte was great. I recommend.

It is really hard to come by coffee shops in Philadelphia with this much expertise. Ross is really great at answering any of your coffee related questions or just to talk coffee.. He roasts his own beans, and they are bright and striking. Definitely going back!

A very quaint oasis in the hustle and bustle of the city. They combine a variety of coffee drinks and bakery items with a modern, hip atmosphere that quiets the noise of the city.

Overall, I really like this place. We came here on a really cold day, so the warm drinks were helpful to shake off the icicles from our wind-whipped faces. The drinks were great, the food is great, and the service was spectacular.

I had the Chai tea latte, and the ratio of milk to tea was perfect; not too milky but not just tea. My friend had a mocha latte and a chocolate croissant. She says the mocha latte had a good balance of sweet and bitter, but the chocolate flavor wasn't all there. The chocolate croissant was tasty, but very flakey.

While we were there, a mother brought her child to the cafe in a stroller, and there are only stairs, so it would be difficult for her to get the stroller into the café. The barista stopped what she was doing, ran to the door, and helped bring the stroller inside. I thought that was the cherry on top of this little coffee shop.

Check this place out if you're looking for a quick bite, fast service, and great drinks!

THE best science-driven coffee experience in Philadelphia. Ross and his team push the limits of how coffee is consumed. Look out for their signature latte, the "coffee shot", or the "Ross-acano". Vibrant Coffee Roasters, their sister company, has super interesting single-origin roasts and blends. If you're anywhere in Philadelphia and consider yourself curious about coffee culture, these guys do it best.

The perfect neighborhood coffee shop. When you travel the world you run across some amazing people and places. Function coffee lab is one of those places. When I look for a good coffee shop I look for two things. One, an owner that has a passion for their profession. Ross is the epitome of that. He clearly has a passion for his art. Ross takes special care to ensure each cup is made to the highest quality. And two, a place where you can walk in and feel comfortable. They have the place detailed and designed to allow the customer to enjoy a cup of coffee. I would strongly recommend this coffee lab to anybody in the area

I’ve lived in south philly for 4 months now and had yet to find my favorite coffee shop.... until right now. Came in here for a cold beverage to complement the beautiful autumn day, and was surprised by the first menu listing: a butternut squash maple latte. Turns out they PURÉE butternut squash n maple syrup and mix it into their latte. Whole milk or go home. It’s amazing, a beautiful hint of earth sweetness, and excellent both hot and on ice. 10/10 recommend. A bit pricey but well worth it. Also they’re a small spot so if you’re there on the weekend make plans to take your bev and walk or snag an outdoor table if you’re lucky. Ily, function.

A celebration of all things coffee geared towards the hardcore coffee nerd. They have all the top of the line equipment and source some of the most amazing beans in the world. Decor is fine, it's a bit small, and service is good.

I hate coffee, but I had the most amazing coffee-based drink here, with lavender jam and I don't even know what. Simply incredible. I tasted the unadulterated coffee my friends bought, too, and even though it was still coffee, it was *interesting*, as in, worth learning to like coffee so I can get to know these drinks better interesting. I will definitely be back.
