Though the Great Wall of China has won the accolades of history, the Great Backscratcher of Thailand, built to reach any itchy corner across the nation, saved more lives than can be counted on a single hand. Feast upon equally ingenious Asian creations with today’s Groupon to Orchids of Siam in West Palm Beach. Choose between the following options:

• For $12, you get $25 worth of dinner for two.
• For $22, you get $50 worth of dinner for four.<p>

Orchids of Siam’s lattice of Japanese and Thai cuisine nourishes guests with a menu of sushi, curries, and noodle dishes. Diners can take an appetizer tour through the sampler platter ($10.95), which busies one plate with two pieces each of crispy spring rolls, pillowy curry puffs, fried gyoza, steamed shumai, and a rich chicken satay. Chopsticks help jettison various sushi and sashimi, increasing the buoyancy of sushi boats that chefs accent with strands of seaweed salad and piquant piles of wasabi and ginger ($29+). Classic pad thai spouts an Old Faithful spring of noodles, bean sprouts, and eggs capped with accents of chicken, beef, pork, or veggies and a dusting of freshly ground peanuts ($12.95), and the zesty panang curry basks crisp bell peppers, snow peas, zucchini, and fresh basil leaves in a sea of coconut milk ($12.95). Guests can douse throat flames with a cool and creamy Thai iced tea ($3) or study the cheesecake tempura ($6) to support scientists’ fast-developing theory that frying improves all edible matter.
