The Mill - no one seems to remember this place
Gator's Shuck N Jive

In the mid-90s, we took clients to a place off of Airline for a decent lunch. Ziggy's? Decor was kinda grandma-ish, but the food was good. ETA: Not Ziggy's. KIVA's. I see it is now Portobello's.

Bonus: Wuvvy's/Captain's Quarters in Gonzales for fishbowls with my friends in the AP.

Was going to add Our Daily Bread, but I see they are still open.
