Harvey's has always been my favourite fast food burger joint but I think A&W is a very strong contender.
I've seen a lot of A&W commercials on the health benefits of their meats like hormone free, pesticide free etc so weird to say, I actually felt healthy for eating a burger! I had the teen burger because it was the only burger that comes with lettuce and tomatos. Gotta have a balanced meal with veggies and a of course a side of fries. While the burger was very juicy and tender, it didn't have that charcoal taste like Harvey's that I like. I was also bummed that my fries were soggy. Harvey's is still my favourite but I think I will occasionally cheat on him with A&W.
