From Philadelphia comes this restaurant specializing in kao yu, Szechuan seafood hot pot, inside Dun Huang Plaza in Asiatown. We’re talking shrimp and whole fish with cabbage, cucumber, pitch-black wood ear mushrooms, and potatoes in bowls filled with chili-spiked oil. If you’re adventurous, skip the seafood and try the frog. You’ll have to dance with the bones, but it’s chock-full of flavor. Xun Yi Si Kao’s bowls are huge and perfect for at least two diners.
