Theory Coffee Company

First time trying it while waiting for my tacos from Naco next to them. They didn't have a menu but they were straight forward and told me what they do and what they had. I got an iced latte with oat milk and house made vanilla (which I loved) and it was good. I'll definitely come back. The wait wasn't long either even given how busy they were at the 8am rush. Great people working inside the truck. Very friendly :)

Great flavors and service. They could better mark where the “Order” and “pick up“ windows are. Apparently the front or street facing one is a pickup window.

Tiny place, big taste.

Out the door early for once, kids needed a pick me up. Came looking for donuts, which from reading reviews looks like they are only on Saturdays? Left with a tasty croissant from Bakery Lorraine and a DELICIOUS latte from Theory. I'm not a coffee connoisseur, but my simple test is good coffee doesn't need any sweetener or flavors- just enjoy the taste of the coffee. This place passed!

I love hole in the wall hidden gems, this place is very deserving of it's high rating! Well manicured cozy place to sit outside, and I like the flair inside!

worth the wait for a cup of home brew just like mom would make! cold brew was slightly bitter but we added some extra coconut milk. the chocolate scone was yum also! the patio tables & shade was nice too

I love this place! It reminds me of a coffee joint back in Georgia (Espresso 41).

I am in San Antonio for a month for training, and a classmate of mine and I go here everyday during lunch. The baristas are extremely knowledgeable, and the coffee is delicious! Every coffee of the day I've had has been amazing. 10/10 recommend!

My husband and I went on a "coffee crawl" for his birthday. Theory Coffee was one we didn't plan, but I'm so glad we stopped. It was absolutely delicious. My only drawback was the limited milk option. I can not stand oat milk, and it was the only option besides regular milk for this lactose intolerant lady. I got regular milk and loved every minute of it (until I didn't). So I just wish for some almond milk on the menu.

If you're a coffee fanatic this will become your favorite stop for some well prepared Joe. Best spot on 410/Naco corner. Coffee, pastries, and great service 6 days a week.

I saw the reviews and eager to try it out, however, this is SA and not ATX coffee. Don't believe all the hype but the food is really good here!!! I got the Keto Taco with Chicken in Green salsa. The coffee on the other hand is meh. I like my coffee strong and it was okay. I would skip the coffee; I got the Latte with honey. I used to live in ATX so they have strong coffee but haven't found a coffee place that is comparable to the strength I like. It is outside seating only and two food trucks. One side is coffee/donuts and the other is solely breakfast food.

Excellent coffee with wonderful staff working efficiently fast and still not missing a drop of the most aromatic flavorful coffee out there. What an excellent convenient location with outdoor tables, shade in a kept clean environment. They're always happy to serve. Like having a coffee with your best friends and family. ☕

Forgot this coffee shops name while doing a birthday coffee crawl with the wife and on the way happened to see a man in a green chevy truck with the sticker on his bumper, so we made the quick trip after seeing it was nearby. Worth it! Great seating, clean area, and inexpensive. No food this trip but awesome coffee and a truly happy crew! Quickly got us our 1 hot americano black and 1 hot latte. Eventually the old green pickup showed up and turns out he was the father of a barrista there. Great advertising for his kid! 4.5/5☆ with the only drawbacks being the tight parking and that its very near the highway so it was traffic loud, but so good otherwise. Will absolutely return anytime im in the area so planning to try the mixed berry danish next trip and hoping to get more stickers too.
