I tried a plain burger and also the Gangnam Korean burger. The Korean kimchi was a nice touch, but they were both very greasy. Even had grease on top of the bun. The plain burger actually tasted a little like a McDonalds burger. I felt bloated the rest of the day too. I just don't understand why burgers like these cost $10 or more.
Just down the street there's a place called Burger Craft that serves lean grass-fed burgers for slightly less price, and without the stomach ache. I'll be going there for my burgers going forward.
