I have visited this place 2 times when I was in Bangalore. Earlier they had a small area which would have a waiting time of around 30min-1 hour on Saturday and Sundays. But during my last visit I saw they have change their place just opposite to earlier place and they have given it a beautiful ambiance!
Food and Presentation: You can never doubt about this one! although I am vegetarian and I have heard from my friends that their non-veg burger items are awesome but they have given proper justice to veg. burgers as well.It is so much tasty:-)
Ambience: The newer one has got a lot more space with two storey and a beautiful ambience.
Customer Service: Although this is a bit on negative side since even after getting a table you have to wait for atleast 20-30 min before getting your food served.
Value For Money: It is bit costly but you can have a great burger at the end of the day which feels your tummy and hence it is worth it.
Overall a must visit to the place for the people living in Bangalore!
