I've been to Shake Shack before in Las Vegas. I didn't really care for it then but I have changed my mind! I've been waiting for the long line to get in to order to die down before I made an attempt at dining here. Luckily, I came by after work and only had to wait about 7 minutes before my order was taken. If you don't know what you want to eat, I would suggest grabbing a paper copy of their menu because it's difficult to see the entire menu while waiting in line. It's usually blocked by other people standing in line waiting to order. The line moved quickly even though the restaurant was extremely crowded. I got my food to go because it was so crowded and loud. There was about a 15 minute wait for my food after I ordered which I was a little disappointed in having to wait so long for a burger and a milkshake but it was a busy night. I ordered the single shack burger with cheese and added onions. It was delicious. Nice and juicy. I didn't even make it out of the parking lot before I dived face first into my burger. I had a limited edition milkshake that was amazing! I don't remember the exact name but it tastes like coffee, chocolate and mints. I can't wait to go back and try out some more items in their menu. It's going to be hard to beat their Shack burger though!
