WRIGLEYVILLE. This casual Greek diner serves up consistently tasty and authentic Greek food to hungry locals, including a mix of students and professionals. Menu items include kebabs, gyros, pita sandwiches, and the restaurant's signature Chicken Kalamata. They also serve several hearty American dishes like burgers and fries. No reservations and virtually zero ambiance means this place isn't fancy, but it is a great value with most items being under $10. Casual dress.

RIVER NORTH. This popular Spanish restaurant once had only four tables, but now it can seat more than 400 with ease. And, the house is usually packed, thanks to authentic tapas offerings and an upbeat, festive atmosphere. Have a fruity pitcher of sangria and order hot and cold appetizer-sized dishes like baked goat cheese, vegetarian Spanish omelets, chicken brochette with caramelized onions or grilled octopus. A gourmet food shop lets you try to recreate your favorites when back at home. Reservations accepted for parties of six or more. EL: Red Line to Chicago/State or Brown Line to Chicago

HYDE PARK. This restaurant offers casual-style Deep South fare in an authentic, down-home setting that includes old license plates, rusty aluminum signs, and even an old timey gas pump. The Southern menu includes such comfort food as fried green tomatoes, johnny cakes with honey butter, blackened catfish fillet, jambalaya, and, of course, well-stocked Louisana gumbo. Full bar.

RIVER NORTH. A must for Chicago first-timers, Ed's is a true Windy City treasure. Reminiscent of a '50s-style roadside diner, the restaurant's retro decor and fun music are always a big hit with guests. After all, this is the place that once sold "Ed's Burp" tee-shirts! While the menu includes homestyle favorites like Ed's Mom's Meatloaf, chicken pot pie, and chicken-fried steak, regulars know that burgers are king here. Go for the always-reliable Ed's Blue Moon Burger or the Route 66, either of which tastes better with a bottle of Ed's Beer. And don't worry: As always, the flurry of insults is free!

HIGHWOOD. This restaurant serves delectable seafood, French-style. Friendly prices, a large wine list, and friendly service all add up to recommend a restaurant that delivers terrific food for everyday dining. Try crab cakes to start, and then consider a salmon filet accented with shallots and sweet bell pepper sauce. Meat and poultry items also abound ­ try sliced pot roast or duck with orange sauce for a taste of the kitchen's bounty.
