Yes, there is a drive through beer barn/convenience store in Huffman, but they don't sell daiquiris or things like that. I confess I've gone through for beer and last minute grocery items. The kids think it's fun.
I10 east, exit Williams in Kenner La. Daiquiri shop there...then into the Harbor Seafood for some great hole in the wall Oysters, crawfish or whatever.
That one place has all sorts of flavors of drinks to go, crawfish, snoballs and much more. Some friends of mine own it and it is very popular. Very Louisiana ! One of my cajun friends thought the drinks were very good! There is a line all the time so they must be doing something right.
The drinks are not Louisiana Daiquiris though. The drive thru shops in Texas can only make them with wine not hard liquor. The closest real Daiquiris are the 2nd exit off I-10 heading into Louisiana. Fortunately, they sell them by the gallon to take home!
