Oh Cassie, that's a stetch, expecially if you want it to be pescatarian friendly on Shelbyville Rd. There is Z's; it's great but pricey. I'd love to say I'd cook that special dinner for you, but I 'm already commited for that evening. Although, if you hubbie wants to cook for you, I can lend you my kitchen and grill.
I'm thinking pescatarian here:
The eastern most place that first comes to mind is Cafe Lou Lou (and it's not very eastern); maybe you should go back to 211 Clover Lane? Havana Rumba also has a "mean" grouper and is but slightly off Shelbyville Rd.
Another possiblity (not on Shelbyville) would be Captain's Quarters. If the rain has stopped the deck would be a wonderful place to reminisce with an old friend. Again going north of Shelbyville is Mitchell’s Fish Market at the Summit which I believe is on its way to going local.
You should consider Napa River Grill north of Shelbyville in the revamped Westport shopping center.
Of course, there is the wonderful Oriental House on Shelbyville Road.
Other than that I'd probably forsake the local restaurant's and go to Carrabbas.
So did you have the "Feed Me Chef" at Limetone yet?
