When picking a sushi restaurant, a good rule of thumb is: Don't go to an empty one. The busier the place, the more likely the fish is moving into the kitchen and out on plates quickly, rather than languishing in a fridge.
Emptiness is rarely a problem at Sushi Rock. The restaurant might be small, dark, and somewhat incongruous (feels a little weird for a Japanese place to be serving a roll called the Red Hot Chili Pepper, which is a variation of a spicy tuna roll, or a dessert called Puff Daddies, which are like tempura-fried cheesecake balls), but it draws a crowd by virtue of its location on main drag Las Olas Boulevard and its earned reputation for good sushi. One day last year, it was so packed that it let actor Alec Baldwin walk away rather than allow him to skip to the front of a line with a 45-minute wait.
