This is more of a philosophical post with regard to a project I'm working on. I'm trying to compile a list of fine dining restaurants that are not local, but are technically chains. I've encountered the usual celebrity chef restaurants a la Wolfgang Puck in NYC, Las Vegas, & LA. However I feel as though I might be missing other restaurants like Le Cirque. Are there any thoughts or suggestions about how I could do this research. Furthermore is there a chain you think I'm missing. Your help would be very much appreciated!
