I don't know that a poor website would keep me from trying a recommended restaurant, but i know for SURE that a good website with a current menu and lots of pictures of the food, dining room and kitchen, and chef bios, would make me more apt to try a place i'd never been. I recently went on a road trip to Cleveland to eat in the demo kitchen at Lola Bistro. I was leaning towards not going until i saw the website. I think as consumers become ever more internet-savvy, a good website will be an invaluable sales tool for high-end restaurants.
