Solid 3 stars. My Texas friends had been telling me about Whataburger for quite a few years. Imagine my surprise when we were driving back to Vegas from Tucson and ran into a Whataburger! Even though it was barely 10am we had to try a burger here.
We got a double burger and found out it doesn't come with cheese! If you add cheese, they add $0.50 per patty, so for a double, it was and extra $1. But the total came out to $6.10 (with tax) so it was a $5.75 burger for a double with cheese. Closest I could compare it with is Farmer Boys if you're familiar. It was much more juicy and hotter than FB.
Cannot compare it with In N Out since the price point is totally different.
In reality, it was a Del Taco Double Del Burger on STEROIDS. The spicy ketchup gave it a bit of edge.
Didn't get a chance to try their fries though, however, we asked for two cups of ice water (for our dogs for our long road trip) and they gave us two large size cups with ice cold agua.
