    Place you must visited

    I had a great experience at Slate at Founders Tower in OKC. The views of the city are absolutely beautiful, especially at sunset, it really sets the tone for a relaxing evening. They offer a wide variety of alcohol and cocktails, so there’s something for everyone no matter your taste. The atmosphere is welcoming, with great music that adds to the overall vibe without being overwhelming. I also love that they host different events, which makes it a place you can keep coming back to, there’s always something new, and it truly caters to a variety of interests. Overall, it’s a perfect spot to unwind, socialize, and enjoy the city from a unique perspective.

    The best experience ever!!

    From our first conversation with the Slate team we knew we had found our venue. They communicated in a way that was straightforward and easy to follow, which made the planning process feel effortless from start to finish. What really set them apart was how they seemed to know what we needed before we even had to ask, they anticipated every detail and went above and beyond to bring our vision to life. The space itself is dreamy and elevated, with moody lighting that created the perfect atmosphere for our celebration. Their high-end approach to every element made our day feel truly special and refined. If you're looking for the perfect venue, Slate at Founders Tower is exactly what you need.

    “The Perfect Place for Our Perfect Day”

    We recently hosted our wedding at this venue, and it exceeded every expectation we had. From the moment we toured the space to the final send-off on our wedding night, everything was handled with professionalism, care, and genuine warmth. The venue itself is absolutely stunning—beautifully maintained, thoughtfully designed, and flexible enough to fit both our ceremony and reception seamlessly. Our guests couldn’t stop complimenting the atmosphere, from the lighting to the layout and overall ambiance. What truly made the experience exceptional, though, was the staff. The team was responsive, organized, and incredibly attentive throughout the entire planning process. On the day of the wedding, everything ran smoothly, and we felt completely at ease knowing we were in such capable hands. They went above and beyond to accommodate our needs and made sure every detail was just right. It allowed us to fully enjoy our day without stress, which is priceless. If you’re looking for a wedding venue that combines beauty, professionalism, and a genuinely supportive team, this is the place. We couldn’t have asked for a better experience and would recommend it without hesitation.
