Pretty tasty burger!! Very modern looking and refreshing. Sadly it's kinda small and people hover to wait for food, so you might want to bring your food elsewhere. However, I discovered that the space at the next door Olive and Ivy marketplace can be shared even though you eat at modern burger!!!! Hurray.
Another tip for travelers, the wait is about 15-20 minutes during meal hours. So gauge your flight timing!!
Finally, on to the food. I got the breakfast burger - bacon, fried egg, patty, lettuce, tomato and delicious mayo like sauce. It wasn't my favorite burger BUT I would definitely try it again next time. The fried egg was a little too cooked for my liking but it wasn't noticeable. You can also get extras or tell them to cook your meat a certain way or remove some toppings. My favorite part of the burger was the sauce!!!! The bread was alright.. Kinda soggy. Not the worst though.
I also got the fries. Mmmm not my favorite and I wouldn't recommend it. Fat and soft. And although it might just have been sitting out for 10 minutes, it was cold when I got it. :(
Overall really good for airport food standard.
