None of them are bad per say.
The biggest problem is that, especially due to inflation, you don't really get a true bang for your buck from any of them and you can get the same shyt for a decent price somewhere else whether it's a mom and pops or a grocery store.
I remember going to Boston Market a year ago and they charged me $15 for a Roasted Chicken Combo. I asked if they made a mistake twice and they said no. I took my drink out and it was still $12 something dollars. I never visited a Boston Market ever again and stuck with buying roasted chicken at the grocery store like I've been doing.
I had a similar experience taking a girl to IHOP. I was legit shocked at how much a simple @ss breakfast with some pancakes cost. Even Greek Diners charge less for the same stuff. Casual dining is ironically more closed off to the average Joe than it's ever been.
I will say that they still serve their purpose for being great for family events or simple dinner dates though. So, they'll always thrive just off that on top of loyal elderly clients.
