One of the best places to experience the strange and wondrous alchemy that is Mexican sushi is also one of the oldest Mex-sushi spots around town: Sushi Sonora. Try the restaurant's take on the cielo, mar, y tierra (a surf-and-turf roll made with shrimp, steak, and chicken), or the deep-fried beauty that is the cronchi roll, which is stuffed with shrimp, imitation crab, and cream cheese. Still, if you want to experience Mexican sushi at its fullest, wackiest expression, you'll want to try the Percheron, a massive roll that's named after the famously oversize draft horse. It's an appropriate moniker for this bulky, tinfoil-wrapped roll, which is crammed with carne asada and bacon and capped with enormous amounts of melted cheese. If you survive the Percheron, you can officially proclaim yourself a Mex-sushi veteran.
