The Shake Shack started as a food cart in Manhattan just over 10 years ago. Now there are over 60 locations across the U.S. This is the Valley's first location. I have been to ones in both Boston and Chicago and have had mixed reviews. I thought I'd wait a few weeks after their opening to dine here. The service definitely wasn't up to par. The server never smiled and looked very unhappy to be working here. He messed up twice placing my order and each time had to walk away to get a manager key (I was overcharged an extra sandwich). This place is pretty pricey. 2 chicken sandwiches, 2 shakes and an order of fries came to just under $30. My son mentioned the bathroom was trashed (his words). My positive is that the food came out relatively quick and was pretty good. The chicken was still pretty hot and tender. The fries are mediocre but the shakes are really tasty. The restaurant itself is nice looking with indoor and outdoor seating. It wasn't too busy when we got here (Monday night), but I hear the lines can be pretty long on busy days. Thumbs up on food and speed, thumbs down on price and service.
