Multiple Michelin-recognized restaurants—Ruan Thai Kung Pao and Baan Ta Ko Rai (both Bib Gourmand)—specialize in grilling these massive prawns over charcoal until the shells char and the meat inside stays succulent. Other recommended spots include Grand Chaopraya, Tonnam Riverview, Baan Mai Rim Nahm, and Phae Krung Kao. The prawns are grilled, steamed, or served in creamy curries. The size shocks first-timers—these aren't shrimp, they're freshwater creatures the length of your forearm.
