I love having the menus available (on whatever site you use). But, never, ever rely on those to be 100% accurate. You can't. I will only choose a place that has at least two things I can enjoy and at least two things my husband can enjoy. The chances of both of what we like being gone is not that likely. I look at the type of food as well.
The only menus that are going to be current are the one posted outside the restaurant the day of your meal and the one you are handed once you sit down.
