While they offer a la carte for dinner, their AYCE lunch experience has our hearts—and our budget's approval. At $14 per person, Madras Mantra’s entirely vegetarian Indian buffet is like a playground for non-meat eaters who want to fill up on more flavorful things than just a boring salad bar. Here, you'll be joined by Decatur’s lunch break buddies, neighborhood regulars, and seniors having meet-ups over crunchy mushroom manchurian. The restaurant is roomy. And the buffet, which does South Indian food very well (the savory beet poriyal and thick eggplant potato curry in particular), moves quickly. So this place works for on-the-clock lunches just as well as it does for days when you want to tuck yourself in a corner with a bowl of hearty tadka dal and tune out the world.
