Hi Betty,
I live in Scottsdale. I used a coupon from restaurants.com once several weeks ago, after reading about the site here on a TUG site. I bought a $50 coupon for a restaurant called Fusions, in old Scottsdale. I was very pleased and really enjoyed the place. With 2 people, including one drink, one dessert and coffee, plus two entrees, our bill came to about $75, we had the $50 coupon, so it was well worth it. Plus the food was excellent. I would really recommend it. (make reservations, although we made ours the same day and it was no problem)
I would do it again if I think about it. I just don't generally go anywhere unless it is last minute.
Gail
