My 21 year old grandson who lives with my wife & I along with My 14 year old grandson who spent the night while my wife is in the hospital for a knee replacement. After leaving the hospital around 7pm we stopped at In-N-Out Burger for a quick dinner. I normally detest fast food, but I don't even think In-N-Out truly belongs in that category.
A lot of people would say In-N-Out is overrated but they are good. They have a very limited menu of get a load of this, all they have is burgers, fries and a few beverages to wash them down.
FOOD: Cooked fresh, our burgers came out hot. They weren't sitting under a heat lamp like some places. It's fast food that's WAY better than any other options out there. For a fast food burger the flavor can't be beat. FYI: I'm NOT a fan of their fries. PRICE: reasonable price. SERVICE: The service was fast and they were really nice.
CONCLUSION: I don't know what the secret is. Chances are you can make a better burger at home, but at the same time there is just something about In-N-Out burgers that makes them delicious. Everything was cooked to perfection! This In N Out is on it! They're at the top of their game to handle soooooooooooo many people and still produce such top notch food!
