The ability to differentiate between red and green curry is the mark of a good Thai chef and a common tell among children faking colorblindness to skip school. Test your rods and cones with today’s Groupon: for $20, you get $40 worth of Thai cuisine and sushi at Sala Thai. Choose from the following locations: Bethesda or on U Street Northwest or Georgia Avenue in Washington DC.

Sala Thai's multitalented chefs prepare fresh sushi rolls that share billing on the menu with traditional Thai cuisine. Meals begin with zesty appetizers such as Pinky in the Blanket—deep-fried shrimp swaddled in an egg-roll wrapper ($6.95). In a split second, the entire table vanishes and reappears in a cloud of curry-scented smoke, revealing sizzling entrees such as chicken lemongrass ($8.95–$12.95) and scallop pad phed with spicy hot chili, garlic, and bamboo shoots ($10.95–$14.95). The diner with the quickest chopstick draw will enjoy the first bite of sushi offerings that include the smoked-salmon-cream-cheese roll ($6).

On most Friday and Saturday nights, each Sala Thai location swings with live jazz, blues, and acoustic tunes. Check the varied schedule for listings of artists such as the Potomac Jazz Project and the Full Ascent Jazz Band.
