That's pretty angry thinking on the part of the restaurateur: I envision people who wouldn't normally get to downtown seeing places they'd make a point to come back to downtown to visit. If I'm going to an outdoor performance of course I'm not going to go to a hoity toity (sp) restaurant that evening. But I may keep it in mind for a future date or business meeting or function. I can assure you I'll remember the name of the restaurant belonging to the complainer, and it won't be for good reasons. It's a fantastic idea and I certainly hope things won't change because of one (or perhaps a few) wet blankets.
