I've been to Roudigan's a couple times. They're just average. They have a great salad bar, but everything else I've ever had was just okay. I could've made a better meal at home. I do remember last time I went in late 2012, I ordered a seafood platter and it was, again, okay, but everything had a lot of breading to it, not much seafood. But granted it was out of season.
I'd go for drinks and appetizers, but not dinner.
A plus, the staff has always been very good, friendly and attentive.
