Margin Cafe is a lovely local gem with a cozy atmosphere and good coffee. This place stole our hearts as it is pet friendly, so we were able to bring our dog! Our barista Fayre was so sweet and handmade all the drinks! Order “for here” to get your coffee in a glass.

A bit overrated. I only recently tried this place, with such a high rating I would figure most coffees are a good choice. But my pals and I bought 3 coffees, two of them weren't great. One just tasted like milk and water, the other just a normal kinda watery coffee. The only good one was the biscoff unfortunately. Maybe it was a bad day for them, but the atmosphere wasn't exceptional. It was just...normal. rather plain, even. I've only been there once, so take this with a grain of salt.

I walked up as they were closing, but the guy said I could do a to go order. I got the seasonal mango matcha, and it did not disappoint. Super creamy, cool and delicious, with real mango chunks. This maybe my new favorite.

The lattes have a nice smoothness, especially getting it hot. This is also a good spot for studying with ports and WiFi, just keep in mind they have a rule where each person has to make a minimum purchase.

This place is a gem, their coffee selection is amazing, I frequent this place at least 3 times a week now and every time is great! I saw below that someone named Jenn Gowdy made a comment about this place, which is kinda of frustrating because none of that is true, they are a small business owned and their operating hour is up to the owners, there are many options around the area if they are early birds, I also wanna say that I myself I have diet restrictions but never blamed any business for my own diet restrictions, last they do have milk alternatives and are FREE OF CHARGE, it’s sad to see this people just don’t know how a 1 star can affect their rating, we should be supporting small businesses.

Margin Cafe Coffee Roaster is a gem in the neighborhood that has been around for three years now. The cafe is well-designed with a clean, minimalistic look that facilitates a focused studying environment or chill hang-out spot.

Run by a wife-and-husband duo that make all the drinks themselves, Margin Coffee Roaster also offers a diverse array of baked goods from a French bakery supplier, such as croissants, cakes, and cookies.

I ordered a mocha frappe with a pure, strong taste of chocolate and coffee. I drank it all in one sitting and devoured the jalapeno and cream cheese croissant. I can see myself coming here again and again for future work sessions.

Miguel was a true blessing to meet as I encountered him and the service he provided to me today. Margin Cafe truly knows how to provide wonderful service and amazing coffee. If you have not been to this location and if you live in the area, you are truly missing out. This place is awesome and when I’m in town I know where to stop by for some amazing coffee.

Delicious coffee at a very reason price! I got an iced biscoff latte with soy milk and loved it! They were able to make it less sweet as I requested, which made the drink perfect for me. Biggest plus is that there is no upcharge for milk alternatives! I’m looking forward to coming here again. The seating is very comfortable and the service is friendly. Very warm atmosphere.

Dietary restrictions: Lots of milk alternative options without additional charge
