Long John Silver's is bundled on the Parkway with an A&W resturaunt, and I will say, the two do make a good pairing for a quick meal- albeit a very pricey meal. Basically, take a standard burger combo, add $2-$4 to the pice, and you'll have yourself an idea of what they charge. Yeah, it's not pretty, and it does hurt the wallet, but the food is good. Especially the Long John Silver combos, which really fill you up.
The draft root-beer with chilled mugs are also a lot of fun, and are very practical, so eat in if you can.
Atmosphere is nice and retro, and the seating is relaxed, but the view of the parkway and all of the speeding cars does kinda kill it. But, if you're with some friends, you can always sit in the corner and avoid the nasty view.
Also, for a "fast-food" place, service can be kinda slow.
On the plus side, they make the best milkshakes out of all of the fast-food joints in the area.
Overall, I don't know what to say. Both resturaunts are OK, but they're both really expensive. And generic. I'd only recomend it if you want to try something different.
