There is a parking garage behind the restaurant. They validate parking for you. Not sure if it makes it free but you don't have to pay the full rate. Maybe a few dollars.
There is a lot connected that is free with validation. However, be careful with DCU events. If there is a big event at the DCU center, there is a person who stands at the garage entrance and takes money as you go in. Though, Mezcal has free valet. It's a better deal to tip the valet than pay the parking attendant on those nights.
When they validate your parking pass, you do not need to give them any form of payment. You still need to put the pass itself into the money machine just outside the door to the garage stairs, but you do not put a form of payment in there either. As far as i can tell you do not pay anything for parking.
The validated parking is free.
The free valet service right in front. No need to park yourself. You should tip the valet though.
There is no fee, parking free. But they also have a valet service
