Eating at my desk is just part of the job working for a west coast hedge fund.

Saves money not buying lunch every day. Usually have leftovers or just eat an apple. I also work from 8:30 to 3 at the latest, so I'd rather have short days than a full lunch hour.
I like bars too and would prefer to go to there for a sporting event. But again, I have a lot of kids and I can't always hang with the fellas or go by myself to a bar. You will find that out soon enough, GB. Especially if you have more than one. So during football season, it is a nice treat to take my sons to Wildwings where we can watch the football games, eat some wings, play some trivia and hang out. There's other options too, but that's just an example. I'm not going to defend their food quality; I just like a spot where everybody is happy.
And if I AM going somewhere alone to eat, I'm going somewhere where I can belly up to the bar, read, have a beer, glance over at ESPN on TV and enjoy the peace and quiet. I sure as hell am not going to a Five Guys where people scream, throw peanut shells and huff down soda.
