Gotta agree with It’s Not Rocket Surgery! - and impossible to name without details.
Just because nothing, Had Fill, Holy I Roll is an anagram of Holly Hill, Florida.
Don’t name it that.

You just need to come up with a story to explain the name.
Mess
I’m actually kinda serious about that. It has a nice double meaning and is ironically “cute” (but then again, I live in San Francisco and EVERYTHING is ironically cute here).
How about something incredibly generic like “World Cafe” or “Global Cafe”?

“Let’s go to That Place.”
Name it like you’d name a rock band, just use some random names/words that sound cool.

If you aren’t decided on what path your cuisine will take yet, something generic that brings to mind the broad type of meals you expect to serve might be best at this juncture.
Something like Shaz’s Diner, or perhaps Holly Hill Diner, if that isn’t taken of course.
Seconding an earlier idea (mostly), Holly Hill Grill gives that lovely rhyming the kids are crazy about.
(Side note, I’ll be in Ormond Beach in mid-April, which is probably not enough time for your restaurant to get off the ground but hey, hopeful.)
I think a great way to name something is to pick something that is euphonious with your name and then leave your name off. Examples would be Marvin’s Marvelous Market becomes Marvelous Market or Bill’s Thrills becomes Thrills. In your case Charlie’s Comfort Cafe would become the Comfort Cafe.
I second It’s Not Rocket Surgery!'s comments.
I also second blondebear’s suggestion of Holly Hill International Grill. If you really do have international comfort food in mind (and there is such a thing, IMHO), the ‘International’ part tells that part of the story, and the ‘Grill’ part suggests comfort food. And the name has a good sound to it, at least to my ear.
Holly Hill Global Grill flows better and is a smidge shorter than “International.”
Otherwise, I’d go with short and sweet: Holly Hill Grill is perfect. If you want to have international comfort foods on the menu, then that’s fine - you don’t have to advertise that in the name. Your name has to draw the dominant market segment of your local population to want to eat there. I doubt Holly Hill Florida is super edgy and hip and cosmopolitan (no offense meant).
Finally, there was a thread here a few years back (?) about a doper starting a local cafe, and realizing that there’s a lot of work that has to go in to it, and how it’s best to have a small-ass menu and set of ingredients to start with (SO limited) and focus on getting people in the door with a small selection of good food done right and done quickly.
Good luck!
Cutesy or novelty names are almost always losers. Go with “Holly Hill Diner” or “Shaz’s Restaurant” or similar.
I think overly descriptive names are almost as bad as cute or novel names. What if it turns out you become famous for your hamburgers and fries? “International Gyro Cafe” starts sounding like a joke.
And don’t go wild on the menu. Go for quality and consistency over variety or quantity. But I’m sure you know that already.

Am I the only one thinking of Babu’s restaurant from Seinfeld?
