Taco Cabana has free flan from 5-8pm today. If you aren't familiar with flan, it's sort of Mexican creme brulee. A firm custard with caramelized sugar syrup.I haven't ever had TC's flan, but I love flan. I don't know if it's nationwide, but locally Taco Cabana also has a "Happy Hour", I think 4pm to 8pm, with $1.50 off any nachos and $1.50 margaritas. So you could get a margarita, a nachos supreme and a flan for about $5 for dinner tonight if you''d like.
