Came in to eat at this location vs the one out by henderson since we were in the area and saw valpak had a mobile device coupon for buy one entree get one free with 2 drink purchase. Valpak even has the option on iphone of adding the coupon to iphone passbook which would only be a mobile coupon you can't print. Ordered presented coupon on phone from mobile app and they said they can't accept it and numerous people have been coming in with that coupon. Good customer service would first of all accepted the coupon they agreed to issue, second have it removed immediately from the mobile valpak add which you use on your phone and don't print and in the mean time post a sign at register identifying problem with not accepting coupon. It's like a retail store almost pulling a bait and switch, if you won't honor something you stop the production of it. All the sriracha bottles and extra teriyaki soda bottle looking things were also sticky and had dust and dried sauce on the top at every table. Cleaning these would take no time each day but if you can't even honor a coupon you issued or revoke it's existence on the app when you won't honor it why would you keep a bottle clean or dust on top of your soft drink dispenser. The food was decent but you need to customer service aka handling coupon issue appropriately and good food to keep a loyal customer only one won't do it. I'll be finding a new spot based on the principal of the issue.
