Reservations are highly recommended for visits to The ONYX. Walk-ins are always welcome and given access on a first come first serve basis. If you would like to reserve a specific time between 7:00pm to 10:00pm in The ONYX, we invite you to reserve your party of 6 or fewer up to 7 days in advance. For larger party reservations please email us.

In order to guarantee all of our guests are seated on time, reservations are allowed a 90-minute stay and your entry is not guaranteed 5 minutes after your reserved time if we are on a current wait. Since there is no business line to The ONYX, and if you are going to be more than 5 minutes late, we ask that you please text us at (602) 456-2366 and we will add your name to the waitlist for the next available entry. We stop taking reservations at 4 PM daily. After 4 PM, names may be added to the waitlist for the same evening in-person only. Wait times quoted are approximate and not guaranteed.

All reservations will be sent a confirmation email and/or text message. 

We like it chill in The ONYX, but…

…Celebrations are welcome and The ONYX is the best spot to play your jams and maybe even dance too. Book your party by contacting us with your estimated group size and food & beverage desires.

Dress code is classy casual, but it’s always fun to dress to impress. 😊
