For prix fixe deals we turned to Kevin Blum of SF City Dish. Kevin’s weekly newsletter, web site and dining card offer great deals and discounts at restaurant citywide and beyond. Here’s what he uncovered for us:

The restaurant list for the 7th Annual Dine About Town has been announced. Dine About Town (DAT) was designed seven years ago to allow customers to try out new restaurants around the city at a reasonable deal. Modeled after restaurant weeks in cities such as New York, DAT features a fixed price lunch and dinner at over 100 restaurants throughout San Francisco. This year, DAT will take place from January 15 - 31.

For a three-course, preset meal, you will pay $21.95 for lunch and $31.95 for dinner at any of the participating restaurants.

Food enthusiasts around the city make a sport out of trying to find the best deals and the best meals that can be had during Dine About Town. While restaurants will continue to be added to the DAT list until opening day on January 15, the current restaurant list features some participants that seem to be good deals or to have interesting menus:

Absinthe (lunch)
Aziza (dinner)
Bacar (dinner)
Big 4 (lunch/dinner)
One Market (lunch/dinner)
Sens (lunch/dinner)

Chowhounds warn of spending more on a DAT meal than you would normally spend at a restaurant for a comparable meal. Examples of this are Chou Chou, Scott Howard, 1550 Hyde and Le Charm — many of which have year-round prix fixe meals for slightly less than the DAT price. An additional tip: when finding DAT deals, check out the actual prix fixe menu. Some restaurants relegate their most boring, pedestrian dishes to the DAT menu, unfortunately.

The rules of Dine About Town:

* You must pay with Visa.
* You must tell the server that you’d like the Dine About Town deal when you arrive.
* The best DAT deals fill up quickly so make a reservation.
* All meals are preset and three courses.
