Most modern cuisine is a continuation of classic dishes, just as a computer is a slightly modified typewriter and a washing machine is a river in a box. Revel in palatable progress with today's Groupon: for $8, you get $16 worth of authentic Indian cuisine at Ruchi Palace. This Groupon is valid at the Irving and Carrolton locations.

At either expansive Ruchi Palace location, customers can browse an authentic Indian menu brimming with vegetables, chicken, goat, seafood, and lamb. Treat bellies to south Indian specialties such as medhu vada, deep-fried lentil donuts ($4), or immerse your tongue in the shrimp vindaloo, where jumbo shrimp and potatoes tread spices in a lake of fiery red chili and vinegar sauce ($13). The rice-laden chicken biryani, ($11) and the Ruchi special lamb fry ($13) arrive at diners' tables sprinkled with herbs and spices.

Ruchi Palace's 5,000-square-foot Irving location houses a sports bar where sportsmen sprint across seven HD TVs before performing crass victory dances next to patrons' foaming mugs; the Carrolton location boasts 10,000 square feet to appease diners who enjoy more elbow room and challenge diners who rely on echolocation to find their seats.
