Stunning. Great End of Trip facilities, the office is gorgeous, beautiful views, the kitchens are great. Dress code varies from team to team, and also day to day. Some days I wear jeans and tshirt, some days slacks and a button up, occasionally a full suit.
Good facilities
Dress code is reasonably flexible, Fridays are typically casual day. But as long as you don't look like you are going out on the town, then it's fine.
