Yes been to a few. Always eat way too much. My law firm in Ontario was close to a Basque restaurant in Chino-lots of dairy cow farmers work and lived there. Some of us would go down there for lunch and come back and couldn't get any word done. There is also one in Nevada we would stop at as we made our way to Wyoming. One thing for certain: even if you don't want to socialize with others you most certainly meet someone that knows someone that knows someone and soon you have something in common-like six degrees of separation.
