I've lived in the Lakeview/Wrigleyville neighborhood for 20 years and, quite honestly, there aren't many restaurants that have been around forever and are gems. (A controversial statement, to be sure.) Add to that the fact Wrigley's a tourist destination and most of the restaurants/bars in the area scream out to be noticed by non-locals.

But...

TAC Quick: (3930 N Sheridan) Family owned Thai restaurant serving a lot of dishes you won't find at the average Americanized Thai restaurant. Ask for the translated menu if it's not freely offered.

Angelina's: (on N. Broadway just south of Addison) Neighborhood Italian restaurant that's been here for 20+ years.

Cafe Orchid (1746 W. Addison at Lincoln): Under-the-radar Turkish restaurant.

Uncommon Ground (3800 N. Clark): Neighborhood place known for locally sourced ingredients, emphasis on seasonal produce, good craft beer list.

Yoshi's (3257 N. Halsted): Japanese-French fusion cuisine. It's a study in contrasts. The owners (he runs the kitchen, she runs the front of the house) opened this restaurant 30+ years ago & it was one of the original fine-dining destinations in Chicago. But it's by no means "fancy." You can sit at the bar, eat a burger & watch a game on TV.
