"Literally so fast! All their menu items are delicious. If you can’t decide, ask one of the fantastic peeps that work there and they will make you something special you are guaranteed to enjoy! Never had a bad experience here. I mean look at this pic of the heavens opening up right behind the OTG. It speaks for itself really. Do yourself a favor and stop by here to grab a drink before you go to work or run your errands, or hit up the river, or do literally anything okay? If you don’t, you’re doing a disservice to yourself."

"As a San Marcos local and coffee connoisseur, I can tell you that On the Grind in San Marcos is the most consistent, fastest serviced, tastiest menu having, and friendliest coffee/beverage spot. The staff is excellent and is always super friendly. Whether you’re in a rush or just needing a pick me up, these guys will SERVE. Also the punchcards are such a nice service for those that frequent them! The drinks are amazing and always high quality, and I know I’ll sound like a broken record here but seriously they’re the most consistent coffee shop in San Marcos and I WILL die on that hill. Go treat yourself and get some On the Grind. Thank me later."

"I love this coffee joint! The girl at the window dressed up as bob ross the painter is so fun! She has a wonderful vibe and presence that makes getting a coffee all that much wonderful here at on the grind. Stop by for your drink is a must"

"Every experience I've had at this has been excellent. The staff are always genuinely courteous, friendly, and welcoming. My Mexican Mocha is always made to perfection & I'm absolutely loving the Bluebonnet Rizer flavor."

"Was told we could order from the window, then the guy at the window told us we couldn’t order because we parked at the employee parking lot, asked where the regular parking was and said they didn’t have any, being first time just wanted a not so rushed experience like other coffee spots, definitely was disappointing."
