word for more frequent than "frequent"

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?

The word that comes to mind to replace frequent here would be avid

I'm an avid restaurant visitor

The word avid has a positive connotation as it refers to showing a keen or enthused interest in the subject matter (restaurants in this case), and holds the implication that you visit restaurants often, as it is an activity that you derive pleasure from.

Definition of Avid: Having or showing a keen interest in or enthusiasm for something.

habitual TFD

done or experienced regularly and repeatedly

Better than obsessive and implies 'you know about eating out'!

always

I forget what the other specific term is but I know it exists. Using "always" figuratively and not literally is a type of hyperbole:

As a figure of speech, it is usually not meant to be taken literally.
Hyperbole

"He is always working."
"He always forgets things."

Nobody seriously takes these to mean "always" literally, as in working 24/7, or that he forgets absolutely everything as if some kind of anterograde amnesiac.

Your example:

"I'm always eating out at restaurants."
