We dined at Papadeaux's once, that was enough for me. It was a solid "OK". Carabba's was "OK". Some of this is because I had low expectations.
McDonald's can be "OK" if you have low enough expectations. I guess they all can be.
There is a seafood place near us we tried, once, "Oceanaire", I later learned they are in the Lindy's group (?). It struck us both as over priced "OK". Never went back.
We can be a bit hard on restaurants. My wife's favorite nicer place near us is called "Ecco", it's part of a group of about 8-10 restaurants of differing styles, and they are all pretty decent. They have outdoor seating which is often a plus for us.
There is a new sports bar type place that opened near us I haven't tried because I'm fairly sure they have ... bar food. Its close to a place called the Sugar Factory, which is always crowded with a very high percentage of black folks, they serve a pretty typical menu, I'm not sure why it has such a racial disparity. I think they have way too many menu varietals and not enough focus, we've never dined there. My wife bought some candy there once or twice (they have a candy story on the side).
