A little caveat before we dive into this review....I haven't had a lot of Indian food in my life. I do like it, it's just not (for unknown reasons) one of the first options that pops into my head when I think about going to a restaurant.
That being said...I liked Sangam and everything we had there. I ordered the chicken tikka masala and it was very good. A little too spicy for me, but I am a total sissy (and I'm sure I was asked how spicy I wanted and I stupidly answered "however he ordered it"). I also tried a few other dishes, I just can't keep my fork to myself, and they were all very good. We had a bottle or two of wine with dinner, they have a good wine list.
Our server was great. She was friendly and attentive and put up with our shenanigans. What more can you ask for?
Definitely a great option if you're looking for some good Indian food in the Lake Norman area.
