Is 1 week in Fukuoka too long?

I have a week off in June this year, and I'm planning to visit Fukuoka. I've already been to Tokyo, Osaka, Kyoto and a bunch of other more "busy" cities in Japan. The purpose of my trip is just to chill, eat some good food, enjoy nice views and potentially meet some other travelers along the way. I'm not really into the whole get up super early and hike a mountain type of trip - I just want something peaceful to escape from the hustle and bustle of my daily life. I am a big foodie though, so I'm definitely looking to have as much good food as I can (Japanese food is my favorite cuisine).

Is Fukuoka a good destination for me to spend a full week? I've heard it's quite boring and there's nothing to do there, but I don't know how true that is. I know there are also some nearby cities but to be honest I'm not much of a day trip kinda person - I prefer staying in one place and really getting a feel for it instead of doing a bunch of day trips where I only get a few hours to see an entire city. So assuming I spend the full 7 days there and don't venture to other cities via bullet train, is a week in Fukuoka too long? Would I find myself bored, or is there enough there to keep me occupied?

Also please share your recommendations on must-go restaurants/bars/whatever, thank you!
