The elevators are actually quite humorous...but good thing they just announced they're expanding to the second floor as well!
Lunch options are slightly limited, but there are tons of order ins and great restaurants nearby to take potential clients or even go out with co-workers for a few drinks.
Just a note: Make sure you you like who you are going to work with, if you don't click well with someone or constantly ask the right questions you could end up not being happy. Work shouldn't be miserable.
