i wasnt here when it was Mac, but I'm presuming so... the office at 155 Bishopsgate.
Everyone has the jitters and a few guys have left already - most of us have a contingency plans up our sleeve just in case it all goes down the can - but we're not exactly short of arcade's to go to round here, I can think of about ten within 5 or 10 mins walk.
Most traders are maintaining the bare minimum they need in their accounts to continue trading, but theres probably still 150 guys in the office here, looking around.
