You’ve experienced a severe anxiety attack.
Since Tony Stark lives in Malibu, the Neptune’s Net restaurant/bar is an appropriate hang-out for him. The production chose not to film the scenes here, probably due to the inability to control traffic on the busy Pacific Coast Highway out front.
Inside Rhodey joins Tony for a brief drink, when Tony suddenly has a panic attack and flees in his Iron Man suit. The Dania Beach Bar & Grill stood in for Neptune’s Net in Malibu, which even has a sign made up to look like the real location in California!
