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 $25 worth of authentic subcontinental cuisine at Coriander Indian Bistro, located an hour northeast of Philly by eunuch-carried palanquin in Voorhees, New Jersey.

Executive chef Vipul Bhasin brings more than 18 years of global cooking experience to Coriander. Eschewing many modern marvels of meal making, Bhasin cooks his cuisine with traditional Indian appliances such as the tandoor oven, the kadai cast-iron pot, and the Aishwarya Rai smoldering gaze in his one-man quest to put microwave repairmen out of work. This passion for tradition is reflected in Coriander's décor: adorning the brightly painted walls are handmade tapestries representing different regions of India, including an astonishingly lifelike one that resembles a parking lot outside an Indian restaurant (look closely and it almost seems to move). Patrons can also unfurl the bamboo blinds between each of the restaurant's booths for a stronger secret-sharing shield than stage whispering.

Despite the traditional tools of the trade, Coriander Indian Bistro infuses centuries-young plate-sharing arrangements with its menu's modern approach to Indian cuisine. Bowling teams celebrating a league victory can split the palak chaat appetizer ($7.99) and revel in crisp spinach touched with yogurt, tamarind, and chutney. Scuba divers on a first date can submerge themselves in myriad entrees, including the beloved tandoori chicken ($16 for full size), marinated in a mix of yogurt, ginger, and garlic, or the rice-based lamb biryani ($16.99), accented with saffron and slow-cooked over an open flame. Traveling tongues will want to opt instead for Coriander's seasonal specials, which take taste buds on a backpacking tour of the hundreds of regional and local cuisines throughout the Hindustani heartland. Vegetarian and vegan dishes are plentiful, as are dishes prepared with no onion and no garlic. So bring today's Groupon, bring friends, and bring fermented drink—Coriander is a BYOB bistro, otherwise known as a BYOBB.

• This restaurant is richly decorated and features such high quality flavorful food...The waiters are friendly and attentive without hovering. It's definitely one of my favorite places when I need my samosa and chicken tikka makhani fix. – Matt C., Yelp
• The naan was fresh and warm, the crispy lasooni gobi (fried cauliflower) and ragda patties were a delicious start to the meal, and the chicken tikka makhani was to die for. Everyone at my table enjoyed their entrees. – Jessica M., Yelp
• Coriander has uncommonly subtle and interesting Indian food in a pleasant dining room. Nicely set tables and good food presentation add to the good dining experience. The wait staff is often charming and personal. This is not a cheap, all-you-can-eat, buffet-type restaurant. This BYOB is proud of its food and serves food that is worth lingering over. – emilee_leblanc, TripAdvisor
