Northern California's increasingly expensive and unsteady economy hasn't led to a shakeout of restaurants, but in another sign that restaurateurs are uneasy Peter Torza has closed his I Dragoni Pizzeria in midtown Sacramento and cut back the days that his adjoining Gianni's Trattoria is open.

I Dragoni, open only two months, just didn't catch on, and to cut losses and to focus on his primary restaurant Torza decided to quickly pull the plug. Over the weekend, he met with employees to discuss options for Gianni's. The group agreed to start closing Tuesdays effective tomorrow to reduce operating costs about 17 percent. While Gianni's has been busy at the end of the week and during weekends, business has slowed appreciably earlier in the week, said Torza. Gianni's already closed Mondays.

Torza also will be trimming some dishes from the Gianni's menu to reduce preparation time and to focus on dishes that already sell well.

"The staff is upbeat and we're trying to come up with better ideas to encourage business," said Torza.
