I wanted to say that
I'm a frequent restaurant visitor
in order to express my authority on the restaurant subject.
But frequent doesn't quite catch it: I visit a restaurant almost every other day. The first word that comes to mind after frequent is often, but you can't say
I'm an often restaurant visitor
Another word that comes to mind is obsessive, but that has other connotations.
What word could I use instead of frequent without rewriting the sentence?
