I haven't mentioned Restaurant.com on here for quite a while. I checked it out tonight & noticed 2 locals restaurants there. I'll keep an eye out for good deals on these certificates. You can often find codes to get them for a few dollars.
This is a good place to check for deals when you are traveling.
The Grande Ranch - on old 30 has certificates available. There's a $10 one for $4 where you have to spend at least $15 & a $15 one for $6 where you have to spend at least $22.50. Tuesday nights they run a great deal on pizza. Don't know if you can combine the deals.
The Pines is also on there. a $15 one for $6 where you have to spend at least $22.50
If you have used them in the past, they will let you exchange old ones for new ones.
