Me and my friend were staying in a nearby hotel and walked around the Rembrandt Square area and came across U6. We each had the Texas Burger and it was fantastic! The fries/chips were out of this world, they had some kind of seasoning on them that was amazing. Not only that but the burger was a decent size and was clearly made of excellent ingredients.
The service was excellent and they young man that served us gave us a lot of ideas about what to see in the city when we asked. I really urge anyone in and around Rembrandt Square to go and eat at this place!
