Lubis! I've never been. Not once. But I remember my childhood friends loving that place.
I would never take someone to three layers for a local jax experience. At least, not for coffee. Maybe for wine and a cigar in the garden, and to show off the rabbit.
Bold Bean is quintessential Jacksonville and our most important tourist attraction. As is French Pantry.
Metro Diner is not of my list and are they're not really local anymore.
Maple Street, also a chain, but I happily take out of town visitors there to taste Jacksonville.
European street? No. Good for beers, maybe...but I would sooner go to Kickbacks. I'm perpetually dumbfounded by European Street. I don't understand the draw of mediocre sandwiches packed with low grade deli meat. I walk/drive by the one on Park street everyday and they ares seemingly always doing well.
I've never visited whitey's or clark's. I'm not a fan of fried seafood platters. And, I've never really heard good things about them either. Seafood in Jax feels like a gimmick, a played out schtick.
Tacolu, I've only been once and I loved it. Based on that experience I think Tacolu tacos beat every other taco I've had in Jacksonville and I've had a lot of tacos in Jacksonville.
