Although Columbus famously "discovered" India by landing at Lexington and Concord and proudly ringing the Liberty Bell, the actual location of India remains a mystery. Today's Groupon offers the best lead the world has had in centuries: for $10, you get $20 worth of Indian cuisine at Delhi Palace.

Voted Best Indian Restaurant in the Free Times' 2010 Best of Columbia readers' poll, Delhi Palace revivifies seasoned palates with its fiery fare and a plethora of handmade Indian breads. Captivate a local scientist without juggling beakers by taking a microscope to the subtleties of the varied menu chock-full of sweet and spicy vegetable- and meat-based dishes. Start the meal with an order of meat samosas stuffed with minced lamb, peas and spices ($3.95 for two pieces) before moving on to hearty meals such as lobster masala ($15.95) and specialties such as lamb madras, its tender lamb pieces tinged with coconut, roasted spices, and curry leaves ($12.95). Instead of rolling a 37-sided die to decide menu items, diners can trust their instinct at the everyday buffet for lunch ($7.99) and Friday–Sunday for dinner ($11.99).
