Is there one place you go to once or twice a week? Why do you go? The food, the staff, the atmosphere?
On Wednesday's I usually go to BW3's.
I've been doing it for about three years. I've got to know the waitresses and the food isn't too bad. It's become a comfort thing. Plus the lunch hour usually stretches into 90 minutes. I sit in the bar and relax watch ESPN or Fox or whatever they have on. When baseball season hits I usually get to watch an inning or two before heading back to work.
At my old job, before they moved, we used to go to a specific Steak N Shake. The waiter that always waited on us was really nice and always gave us free drinks. The food was just typical SnS food, but the service was worth it. Around where I work now, there really aren't any good sit down spots, and if I get lunch, I usually drive through or get take out. I live close enough to where I work that I can just go home for lunch.
I rarely leave the office for lunch, but when I do I meet my old secretary at Kyoto's Express! It is a Japanese steak house, like the one's they cook in front of you, but it is a fast food version of the more expensive restaurant. You can still see him cook, only he cooks for everyone, not just for your table! The food is the exact same- even the huge portions, but faster and cheaper!
