Bought a $25 coupon from restaurant.com for buffalo cantina, attempted to use coupon on front door copy of coupon stating that it does not accept the coupon. I believe that Restaurant.com is a scam, and that restaurant.com is making a LOT of $$$ selling these bogus coupons. Buffalo Cantina does not issue the coupon, so it does not honor the coupon. Buffalo Cantina is still a great place to eat.
