Le Boxx Cafe is open for three hours every week day. It was only by a stroke of weird fortune that I was even able to visit this place for lunch.
I didn't love it. I seem to remember a lot of people commenting that Le Boxx is great, and the ratings on Urbanspoon seem fairly flattering as well. However, when I was finally able to visit, I had a lackluster experience.
I didn't find any of the menu options ground-breaking, and my lunch wasn't fantastic. My coworker didn't seem thrilled with his selection either. Our waiter was mostly... well, not there, and not interested in meeting my requests (no pickles? seriously?).
Le Boxx is a GIANT space, so I imagine they make some money from large-crowd events. They also deliver box lunches (duh), which may be their bread and butter. I can't imagine that they stay in business solely due to their meager lunch hours-- there didn't seem to be a ton of people in the cafe when we were there at peak lunch time.
So bottom line: not fantastic. If I were in area for lunch, I'd go immediately next door to Cafe Martin any day.
