The larger seating area we're speaking of, is considered flex-space and is often used for special dining events, most of which are seasonal.
Food offerings in the cafe-style restaurant now include Tex-Mex flavors, mostly built around chicken or steak fajita stuffings. Tex-Mex isn't something that you can readily find at other SeaWorld dining locations, and so the new offerings are a welcome change to what had been there before.
Prior to this change (which happened in the late-spring of 2015), the Seafire Inn had been offering cafe-style entrées... Including a Hand Carved Roast Turkey Sandwich, Fish and Chips, a Mediterranean Veggie Wrap, and Chicken Stir Fry.
