I really like Five Guys Burgers. A few of my friends were underwhelmed by the burgers/prices/whatever, but I'm definitely a fan. It seems that people constantly draw comparisons to In-N-Out (and I get why), but the burgers are a lot bigger here and there are so many toppings to choose from; it just isn't the same thing.
Pros:
Gigantic Burgers! I got a bacon cheeseburger (with 2 patties, which is the default size) with jalapenos, onions, lettuce, tomato, and a bunch of other stuff I can't remember. This thing was about 5 inches tall and weighed like 20lbs*.
Fresh Jalapenos!! This is a big one for me. It's very, very rare that any place uses fresh jalapenos as a topping. It's always the slices that come in a jar soaking in vinegar and are dark green and not spicy. Those are good on nachos. You know what's better on nachos? Fresh jalapenos! They're better on everything, and Five Guys recognizes this. Well done, chaps!
Peanuts while you wait! I don't really care for peanut, but the option is nice. You just grab a paper tray and fill it with some peanuts while you wait for your monster burger to be cooked.
Flavor! As with the jalapenos, the other toppings are all fresh and delicious. The bun has a nice flavor to it, and the beef tastes great. I like my burgers medium-rare, but these patties have a nice charred exterior and taste great.
Bacon!! I feel like I don't have to comment on this one. It's bacon.
Cons:
The bun. While it tastes great, it isn't really substantial enough for mammoth-sized burger duties. It's really soft, which unfortunately leads to the bottom bun getting overwhelmed with burger juices. About halfway through my burger I had messy hands and was essentially just holding on to the patty on the bottom. The top doesn't get as bad, but it still doesn't hold up. Toasting the bun would likely help, or even putting the lettuce on the bottom would prevent the bottom from getting soaked.
The fries. I don't usually like fries, but I felt like I had to try these. A lot of people talk about how good the fries are, and it's in the name, so, why not? I didn't care for them at all. They do give you a lot, though, so if you like fries, you might like these.
Five Guys is quickly becoming my favorite burger chain. With it's gigantic, flavorful burgers and it's fairly reasonable prices (I think the bacon double cheeseburger is like 6 bucks. Not bad for almost a day's worth of food), you can't really go wrong.
*That's definitely an exaggeration, but it was hefty!
