(WSYR) – A restaurant chain is celebrating National Queso Day by giving out free cups of the “liquid gold.”

Moe’s Southwest Grill is celebrating National Queso Day, which is Wednesday, Sept. 20, with a multi-day promotion filled with free cheese: Now through Sept. 24, all guests can get a free cup of queso (one per day) at participating Moe’s locations nationwide, no purchase necessary. 

Of course, there’s a small catch. In order to get the free queso, customers have to be members of the Moe’s Rewards program. Thankfully for queso lovers, it’s free to sign up by just downloading the smartphone app and creating an account.
