Wow yelp...really should get that \""zero star\"" set out for this place!  AWFUL, HORRIBLE, YUCK, and pitiful customer service.  \n\nMy husband and I are new to Arizona and I had bought a groupon for this place in hopes to find us a new favorite spot to go in our new hometown.  I was at first pleasantly surprised by our waitress who seemed nice and knowledgeable.  She took our drink order and gave us some time to get a feel for the menu.  We also ordered an appetizer of onion rings.  Onion rings were ok, drinks had no detectable alcohol in them, which is strange for rum and coke, haven't ever had that issue before.  I asked her to take away and off of my bill.  She did.  She told us that a great \""share\"" dinner would be one of their combo platters.  So we ordered the platter with beef brisket, beef ribs, and a quarter piece of chicken which also came with a side of steak fries and mac n cheese.  We waited, and waited, and waited some more.  About 30 or so minutes later she arrives.  We expected a PLATTER, especially for the $22 price tag.  What we got was a regular 9 inch dinner plate with a bowl of about 1/2 cup of mac n cheese on it along with the meats and fries.  We both looked for another plate thinking, \""This can't possibly be it\"".  It was.  I think that it sat under a heat lamp for 20 of those minutes we had waited, and maybe on the counter for another 10.  Everything was dry and the BBQ sauce, OMG, awful.  And the food was cold.  Our waitress was gone for a long time, long enough for the bus boy to come around, seeing that we were just sitting there, and ask if he could take our plate which still had the food on it.  Once our waitress did surface, I told her that everything was dry and not good at all.  She said, \""Oh sorry\"".  She did ask if she could bring us anything else, but disappointment after disappointment, we declined.  The final bill was under what the groupon had allotted, so we left it and went to go to car to leave.  She comes running out after saying that she needed more money.  ARE YOU KIDDING ME?  I don't even think we should have to pay for something so awful and here you come asking for more money?  She said that the groupon didn't cover the few bucks in tax.  I was amazed.  Save some face Dillon's...that is ridiculous.  I have never been to a restaurant that didn't comp food that was not to a customer's liking.  Especially when it was this bad.  Again, should have checked the reviews here on yelp...when will I learn that lesson (lol)?  I think it has sunk in now!  \n\nLet me add in that I am a little picky when it comes to food, however, my husband is not.  He will NOT waste food...but wouldn't eat this...THAT is a true testament to how bad it was.  I have never seen him waste food in the 8 years I have known him.
