Amber's claim to fame is definitely their lunch buffet. For a weekday lunch they have a lot of choice and very good food. At around $12 it is very reasonable on the pocket too. I would recommend that your first trip to amber be for their lunch buffet to get a feel of what you like or don't like.
If you decide to go a la carte, it can be a hit or miss. I tried a bunch of items on various visit. As a rule of thumb, the South Indian food (dosa's, avial curry, etc.) is good and stay away from the info Chinese food. For example - Stay away from mushroom chilly Manchurian. They were some very big pieces with the batter kind of leaving a weird after taste.
That said, their a la carte quantities are quite generous. A usual rice and gravy can easily have left overs for another meal.
Another option to sample a variety of dishes is their combination dinner for two. Again there was enough left over for both of us for another meal.
Pay cash if you can. They don't tell you this, but they charge a 4% convenience fee on card transactions.
Someone commented about the songs on TV. Well, that is Indian entertainment for you. These are song and dance numbers from Indian movies and is the way we roll. If you don't like it, consider Dhaba a little further down the road.
