There should be plenty of options to pick from at Disney Springs for a picky eater - if not into adventurous 'interntional' cuisines, there are always places like Rainforest and T-Rex that are kind of like Applebees/Fridays/Chilis general American food. Quick serve include Chicken Guy, DLuxe Burger, Blaze Pizza that are all generic American foods. Frontera Cocina is OK Mexican - it's not full Mexico authentic, but good. Paradiso also has some Mexican/Caribbean type dishes, Americanized. Art Smith's Homecomin' is a favorite for fried chickens and southern comfort dishes, and Summer House has good higher end Americanish foods and some healthier selections too that should suit a non-adventurous palate. House of Blues is also southern/American comfort food, with bar type foods at City Works and Splitsville (everything from burgers and chicken sandwiches, salads, and street tacos). Raglan Road is technically 'Irish', but the menu is vast and would relate to anyone looking for American foods - steaks, meatloafs, chickens, potatoes, etc...and is always a reliable spot with good food and entertainment too.
I've eaten at all - and don't have any bad reviews for any of them...they may not be my favorite restaurants of all time, but are reliable, decent quality and well cooked/seasoned. I also like Morimoto, Wine Bar George, Enzo's Hideaway, Polite Pig, Jock Lindsay's, and Boathouse. I haven't eaten at Paddlefish as I'm not a seafood person. Terralina is OK, Edison is OK, STK is OK, and Maria & Enzo's is OK - they just don't jump out at me so I often skip them.
