There's really no cajun places around me. There's a Razoo's (if you know what that is). They have great food .... especially the gator tail chips.
As far as sweet tea ..... I have a "tea maker". Just pour in 8 cups of water, put 3 or 4 tea bags in (large ones), and press the button. When finished brewing, add water until you have 1 gallon total. Stir in sugar. Use ice for immediate consumption. Refrigerate. I put 1 3/4 cups in mine ..... but I know others that put over 2 cups. Nothin' like sweet tea. Most people use diablo's method. You can also use a coffee pot.
