From my past experiences, I now don't,
eat out on Valentine's day. Crappy food, service and over priced.
eat during restaurant week. Some great deals to be found but usually the menu is pretty boring
consisting of either chicken or salmon. Service is usually not as great either.
order specials without asking prices first. I think I really got cheated a few times by not asking how much today's specials were.
order a lot of food if their bread is not good- To me good bread is a good indication of the quality of foods that are served in that particular restaurant.
go out to eat on holidays like Thanksgiving and Christmas. I just feel bad for chefs and other helpers who can't be home to celebrate holidays with their family...like my brother in law....who has never been able to celebrate thanksgiving and christmas with his family.
What lessons have you learned?
