After a few hours of looking around, I came across this thread and got a huge smile. I lived in Argyle for 10 years and went to Irma's every weekend ( almost ) with my dad. I can't imagine ridding there from Monroe in the winter ( did you take Hwy. 81? ) Im in Monroe now but went to Irma's a few months ago, still great food.
As for you guys asking about the waitress, If 'Becca was there im sure he was flirting lol, went to school with her.
