I will not return to The Grapevine.  We went on a fairly busy Sunday afternoon and the staff was not up to the challenge.  The hostess disappeared for several minutes at a time, leaving many people wondering who to speak to, what to do, or whether they should seat themselves.  When we did get seated, the waitress was even more clueless.  She didn't show up for several minutes, then took a drink order and disappeared indefinitely.  Every time she did anything she was gone for an inordinate amount of time before returning.  This became especially annoying when she gave each of our party of three drink refills one at a time. When the food finally arrived, it was no longer warm, so whatever she had been doing she allowed our food to sit for awhile before she brought it.  Bottom line: the staff had no idea what they were doing and were extremely slow in doing anything.  I now see that this slow service runs through all the Yelp reviews.  Now the food: not horrible, but below average.  Definitely not worth the wait.  The menu spans lavosh, mexican, burgers and gyros.  Too broad a choice for most chefs, and this one was no different.  The chips and salsa were good, and the chips homemade, but that was the extent of it. The rest of the food was very mediocre and room temperature.  There are many good places in the Old Town Scottsdale area, and The Grapevine just doesn't measure up.  You can get better service and better food at many other places in that area.  (As a trivial aside, an example of how clueless the staff was is that on a Sunday afternoon, they had the bar TVs on bowling.  Yes, Bowling!!)
