Chicago's restaurant community is doing its part to help survivors of the devastating earthquake in Haiti.

Among the efforts:
From Monday to Jan. 24, 32 (and counting) area restaurants will offer diners the opportunity to add $1 to their tab. The total collected will be donated to the nonprofit Heartland Alliance, which has set up an emergency fund for quake survivors.

Buy a burger at DMK Burger Bar, 2954 N. Sheffield, between Tuesday and Jan. 24, and 25% of the proceeds will go to the American Red Cross Haitian Relief Fund or Share our Strength. The burger bar also is hosting a raffle ($20 a ticket) to win a month of free burgers. The drawing will be at midnight Jan. 30. Donations will also go toward relief efforts.

Hearty, 3819 N. Broadway, will forward five percent of its gross sales through Saturday to the International Medical Corps, which is assisting Haiti with health care services.
