Hands down, Long John Silvers has the best fried fish and I'm not joking. I've been going there since I was a kid, and I've never been disappointed, and that's coming from someone who doesn't really like fish. The fish is of great quality and the crispy batter is delicious. The cole slaw is also tasty. The one thing that could be improved upon are the fries, but the hushpuppies kind of make up for that.
This particular location is very clean, and has a fun nautical diner-like interior. The manager of the place is super nice and always greets me and my family when we come in. I just wish the location was closer to home--they need to open some LJS restaurants in Scottsdale!
