Palace Truck Stop & Game Room

You can see the sign with a few bulbs out from the 510 at the Almonaster exit. When taking the exit, follow the Chalmette arrow and keep your eye on the sign. It is a bit tucked out of the way, not frequented by huge crowds. They have decent gas prices, a clean restroom, and if your a trucker, they have several amenities. The convenance store is clean and well stocked. It can be a bit scary at night, but that is because there is nothing but trees and swamps in the immediate vicinity. They have scales for the big rigs and a separate area for the big rigs to fuel. They allow rental of spots for large trailers, warehouse space that I understand can be rented.
If you are in the area, come get your cheap gas on, even if it looks semi-​questionable. Just have some situational awareness, and you will be fine.
