Melt Bar is a fad food, and I wonder how long it will be trendy for. Of course it's tasty. It's carbs and fat. The french fries are delicious and you're in glutton heaven for the first 15 minutes of your meal, followed by a possible tummy ache or guilt.
But is this worth a 2 hour 45 minute wait? Let me put this into perspective. You could watch one of the LOTR trilogy movies in this time.
The restaurant's design is purposefully inefficient to make you wait and hopefully buy drinks at the bar. They make you wait to build a perception of quality and desire.
Unless you come at off-peak hours, do yourself a favor: buy 2 pieces of texas toast, drench them in butter, put a 1/2 pound of your favorite meats, cheeses, veggies, etc in the middle, and double fry your fries.
And then eat that while watching LOTR at home. :p DIY
