Reza's (Persian food) has an all-you-can-eat lunch buffet on weekdays for about $10. I think on Saturdays they have the same thing but for a couple of dollars more, and there's a brunch buffet on Sundays---call them for current price. Also, for a modest Swedish lunch look at the menu in the window of Svea.
M. Henry is best known for its breakfast type items (eggs, pancakes, etc) but at lunchtime they also have salads, soups, and sandwiches available. You can view their menu, with prices, on their website at www.mhenry.net
Big Jones has "Southern coastal cuisine" including Cajun/Creole specialties as well as those from other parts of the South. They are open for brunch/lunch every day; however, their website ( www.bigjoneschicago.com ) only shows their brunch menu (with prices), not whatever variation they have for lunch during the week. I've only eaten there for brunch, but it was excellent (particularly the complimentary beignets).
Huey's Hot Dogs for great Chicago style dogs and fries plus I love the blue cheese burgers.

Taste of Lebanon - great falfels and shawarma wraps. Beware that you will smell like oil upon leaving

Edgewater Lounge - a little bit off the Andersonville main stretch but I love the food. The menu far exceeds the typical bar food. Try the chili,. Plus the fries are hand cut.

Andies has been on my down-hill list lately. I haven't had a good meal there the last three times I visited. We used to go at least once a month and it just seems lacking.
Hopleaf is an excellent suggestion. However the kitchen does not open until 5 pm.
