The Swiss are known for their excellent timepieces. It's that same care that goes into the pecan pie at Roland's Swiss Pastry and Bistro (6504 Del Monte, 713-785-4294). The mid-size version ($3.50), about the size of a personal pan pizza, may seem too large for one person until you take the first bite. That's when you'll wish they'd supersized it. No need to worry about burned or raw pecans, or too much or too little liquid in the filling. Don't give a thought about whether the pastry shell is over- or undercooked. Just sink your teeth into a precisely executed, delightful pecan pie with a correct crust, perfect pecans and flawless filling.
