Keenan was an excellent server. As a server myself I look forward to seeing how others treat their guest. Keenan definitely met my expectations & will be asking for him every time. Keep doing you brotha! You were wonderful!!!

My husband and I absolutely love this restaurant! The food is amazing, no matter what we order. Their taco Tuesday deals make this place perfect for date nights. I recommend this place to everyone and anyone that will listen. The servers are always fantastic, even when they are overwhelmingly busy. If I were on death row, my last meal would come from this kitchen! 🤤

We went to Rio’s for the first time today. It was a great experience overall, but the service was like icing on the cake! The hostess, Alecia, greeted us with a friendly vibe, and made us feel welcome. Our server, Keenan, was prompt and polite, and is definitely a good fit for the position! We’d eat here again, for sure!
