Usually it is grilling, but in my experience, what is grilled will vary. And there will be salads along side. Unfortunately a lot of macaroni salads or very mayo-laden potato salads, depending on where you go. Corn on the cob, however, is always welcome (to me). Best grilling is home-made burgers (meat and/or veggie - AND the veggie ones should be real, rather than pretending to taste like meat), and cut-up chicken that doesn't skimp on the dark meat. Yes, I even prefer the backbone to the breast, especially grilled! The corn typically is wrapped in foil and will generally end up on the grill, too.
A few places I've been.... grilled veggie shish kebabs. I can definitely go there!
