You guys are funny!

You're making me want to go back - and we just got home!
Conch Fritters has conch fritters and cracked conch.
Linda's tiny stand in the dock building also has both, (I think) when she's open. (If anyone really wants to taste conch in Nassau and only wants to take the minimum number of steps away from the ship, this is your best bet...)
Imperial Takeaway only has cracked conch (but other stuff on their menu, too.) But, they do offer the canned Goombay Punch, in addition to Coke, Sprite, root beer, etc. YUM! Non-alcoholic pineapply soda famous in the Bahamas...
A quick anecdote from our recent visit to Imperial -
We were sitting there, tucking into our styrofoam trough of cracked conch and fries and chatting with locals about Hurricane Irene. While we're there, a steady stream of locals pick up their orders and leave with their bags, including one woman office worker who looks like she's picking up enough for a small group. A teen emerges from behind the order/pickup counter (two windows in the back wall) and sloooooooowly starts emptying the trashcan near the tables. Suddenly, the women behind the windows start yelling to the teen to "go get that woman" - the office worker - who has just left - "she's left one bag behind." (She's been out the door for about 15 seconds.) He glances up and says "Naw" and returns his attention to his trash can. The women exclaim loudly and race out from the back with the bag - just in time to bump into the returning woman who is back at the doorway and has realized she's missing something. The woman cluck and fuss at the teen, who seems unfazed. Even the locals were chuckling and shaking their heads at him!
If you do go to Imperial - remember it is a LOCAL place and not gussied up (AT ALL) for the tourists. We enjoy finding places like this when we travel, but not everyone does...
Have fun with your taste tests! The just-caught conch for the cold salad sounds divine!
