I do not eat fast food often, I'd rather make a tuna sandwich if I get hungry with no options. A Five Guys opened near us and I suggested we try it this past summer when we were in the middle of a pandemic yard work frenzy and I'd signed up for Door Dash. Have to admit that it was pretty good. We've ordered once or twice since. Love that you can customize the burgers and that they come in small sizes.
I hadn't eaten there until last summer when I had a layover and was hungry. I figured I'd try it because of all the hype around Chick-Fil-A. I had a grilled chicken sandwich and I was underwhelmed. When I arrived at my sister's house, I told her that I'd tried CFA and wasn't wowed. Her being a huge fan of CFA, she took me to her local place where we waited on a huge line in order for me to order a grilled chicken sandwich that was slightly better than the airport, but nothing I'd rush back for. She told me I had to order the fried chicken, its better. I prefer grilled, so I guess I'll never know. Didn't know about the milkshake, but it sounds refreshing.
