At night, the scene at this Indian restaurant in Cumberland stays relatively quiet, aside from the Bollywood music videos on the TV and a few families sharing thalis of creamy paneer butter masala, tasty dal, and gulab jamun. But when Swapna opens its lunch buffet, the place really comes alive. Forks clank and folks shuffle out of booths to go for their umpteenth helping of tandoori chicken. Come then. The rotating buffet is the best way to try Swapna's various North and South Indian dishes and Indo-Chinese staples. Yes, we’re looking at you, crispy mushroom manchurian, creamy sambar, and those flaming red, expertly spiced tandoori chicken thighs.
