This 4-year-old outpost of the Hillstone Restaurant Group (Houston's, Gulfstream) might not have the history or trendy cachet of some of its listmates, but its central location and comfortable walnut-wood dining room has execs and agents keeping standing reservations. "It's an upscale environment that feels familiar," says executive GM Rob McClain. From the seared tuna salad to the French dip, SBG offers a nearly foolproof menu and free lunchtime valet. Regulars like manager Peter Principato and Gersh's Christopher can walk around the corner from their offices. The convenience saves time and energy for work: "When I'm in foodie mode, I'll look at the latest places," says entertainment attorney Nina Shaw. "When I'm thinking about business, I don't want to think about the menu. I want a good meal and consistency. It meets all of those requirements."
