I had an offer from Restaurant.com for a free ten dollar certificate so I chose Tacos & Tequila at Luxor, because it is next to our hotel and I love tequila. Now I am wondering if I should actually buy some other coupons from R.com for Border Grill or Aureole before we visit LV in a couple of weeks. I will be using a certficate for the first time and I am trying to decide between just trying it once and then planning for the next LV (cuz there is always another LV trip); OR will I kick myself for not getting coupons? When did you first try the coupons (it could be Groupon as well)? Do you end up buying MORE food bc of the discount? Would you recommend it to a friend? Any thoughts welcome!
