Not a bad Indian buffet, all things considered. Compared to the several others in the area - Minerva's, Dhaba, Kangchen, Swagat - it's above average. I think they excel most in variety, with the second-largest selection of options within the list I provided, as well as having a good proportion of non-vegetarian options. They have some of my favorite desserts - kheer and gulab jamun - and their mango lassi doesn't taste too sweet or artificial.
However, I must confess that Swagat does out-do Amber in terms of flavor. With a similarly large selection of options, Swagat's dishes are a bit more potently spiced. When I have Indian food, I should be able to barely handle the intensity and complexity of the spice. At Amber, I don't think I particularly noted the spice. So I guess come here if you're particularly afraid of spice? But then why would you be at an Indian restaurant if you didn't want intense flavors...
