It’s essentially in the middle of the restaurant itself - not a separate space. So think general dress code guidance for CG applies. Dress shorts are fine. I’m not sure I’d feel comfortable in workout/athletic shorts. If trying to go, suggest you try right at open. It fills quickly and you might not be allowed up if full (you have to check at the podium on the 2nd floor to see if there’s room; if there is they’ll escort you up on dedicated elevator). Sushi or the goat cheese ravioli or a flatbread are our favorite bites.
