This my first post, so I just wanted to get my preferences out there. Having lived here almost half a century, I can say that some of Wichita's best food places are gone forever. But here are some personal favorites from a Clean Plate Ranger.
BBQ: Hog Wild (west street), B & C Barbecue, Jet Bar-B-Que
Mexican: Connie's is the oldest and still the best; family owned. Plaza Azul is good and inexpensive. Abuelos is upscale and the food is good. Felipe's is nice. The food at El Paisa is decent but the service is spotty. Margarita's Cantina is a decent lunch spot.
Italian: Carrabas is upscale but good. DeFazio's used to be good, but has gone way downhill. Angelos, which was the best, is out of business. Savute's has definitely seen better days. In short, there's a lack of decent Eye-Tie here.
Hamburgers: Hands down, The Oasis. Ty's Diner is a very close second, especially because of the fries. Bionic Burger also is nice. Red Robin is a chain but quite tasty.
Breakfast: Riverside Cafe, The Beacon, King's X (north), The Good Egg, Jeanne's Cafe, Jimmie's Diner. In that order.
Latin: Sabor's is new and the hot spot and very good.
Thai: Thai Tradition is the best, but Bangkok Thai Restaurant is a good second choice.
Lebanese: N & J is the best, but Byblos is perfectly good and a bit friendlier.
Deli/Sandwich: Planet Sub is the best. Cinnamon's is OK, and a lot of people like Panera.
Anytime: Nu-Way (on west Douglas - the best!), Old Mill Tasty Shop, Copper Oven, Le Monde, Scotch and Sirloin (VERY expensive), Texas Roadhouse, Freddy's
Japanese/Sushi: Sumo, Hana Cafe, Emperor's Grill (called "Empies" locally - inexpensive), Kobe
Coffee: Riverside Perk, the Vagabond (called "The Vadge" by locals).
Avoid despite what they say: Granite City, River City Brewery, Ted's Montana Grill, Pig In Pig Out, Two Brothers BBQ, Player's, Town & Country Restaurant, Whiskey Creek Steakhouse.
Later: The Kansas Ciy scene...
