Miami is home to some amazing restaurants, but often times, they are more than you want to spend.
From August 1 to September 30, you get a wonderful opportunity to check out some of the pricier dining options, and get a three course meal, at a fixed menu price of $39.
Here is a nice writeup from the New Times, about all of the 181 participating restaurants.
And here is the Miami Spice website, to check out the various restaurants, where you can search by lunch/dinner, nights they are participating in Miami Spice, by cuisine, and by area.

Some tips:
-Make sure the restaurant is honoring the Miami Spice menu on the day/time you plan on going. Not all restaurants honor it every day.
-Check out the Miami Spice menu beforehand. Some restaurants have more options than others for their Miami Spice menu. (They will have their regular menu as well to choose from when you go.)
-Make a reservation. Restaurants get very busy for Miami Spice, so try and call at least a few days before to make sure you can get a table at the time you want.
Happy dining!
