Strip buffet question

Trying to plan our itinerary for our upcoming trip..... Can we use our Wicked Spoon@Cosmo coupon and our Cravings @Mirage coupon any day, or just Monday thru Thursday?

My wife and I used the Mirage Cravings one on a Sunday for brunch.

Thank you! We are staying downtown for the first time in 20 years......... Only tim we plan on going to The Strip in Friday for Elton John show, Hoping to use one at lunch, one at dinner,
