One of my fave burger places to eat lunch or dinner at. Juicy burgers and more than enough fries. If you haven't tried Five Guys, you're missing out. ;) read more

Good stuff burgers but it is a bit annoying how they congradulate themselves all over their walls.

$22 plus for a double cheese burger and a little bacon cheese burger a large fry and one small drink? It was ok but sure not worth that amount! read more

Pretty ordinary hamburgers, nothing to get excited about. Service is okay but you do have to wait a while for your food. The whole decorating theme is bags of peanuts stacked up and lots of articles about how great Five Guys is. I love burgers but I doubt I'll go back, because the food isn't any better than something you'd get from a drive thru. read more

Totally different than in n out. I love both places. If you've never tried Five Guys and you already love in n out you gotta try it. You won't be disappointed. And they are always super generous with their fries. read more

$3.09 for small fry and $2.50 for a small soda. Plus a little burger my lunch was $12.17. I've been to high end restaurants that charge less for fries and a soda. This is ridiculous. read more

Not usually a huge beef or burger fan but-Yes. The best Burger I've had in Vacaville in a while. Super juicy, loaded with all the goodies, been here just three times and always cooked perfect! The Cajun Fries are perfect too. Atmosphere is cafe like and cozy- Marcus and crew do a great job. See you guys soon @ Napoli's! read more

This place is never a disappointment! I tried the burgers & the hot dogs all the way & nothing but mouth watering excitement!

Ate the messy hamburger here and it was all good. How can you ding a place that also offers you all the FREE roasted peanuts you can eat and let's you know where the wall of 50lb bags of potatoes sitting on the floor are from? This day they were from American Falls, ID. They even had Cherry Coke. Service was excellent. read more

We drove around the Nut Tree parking lot, trying to to find this place. The sign only faces 1 way, so it took a bit to finally find it. The burgers are fine, though they looked very smushed together. The bun barely made it through the process of eating the burger. I liked the sauteed mushrooms a lot; the sauteed onions needed to be cooked a bit longer. However, the burger meat was woefully under-seasoned. I am so not a salt freak, so for me to even notice was worth a comment. The fries needed more salt, too. Fries were good, much better than In N Out (I absolutely hate In N Out fries!!!). . Five Guys is another pricey burger joint. We spent over $20 and just got 2 burgers, 1 serving of fries and 2 regular sodas. The peanuts were free . . . I would rather go to Fenton's and get a burger there. read more

I'm not impressed with the food here. While there is a wide selection of toppings it doesn't mask that the burgers are generic meat patties. I will say that the Cajun fries are decent so if you care less about taste of the burger then I'd recommend this place. read more

I have my own restaurant that specializes in burgers. So finding a place that meets my expectations is few and far between. But I do have to say when I left, I bought another burger for the road. Will eat here next time I am passing through the area. Good food read more

After eating here a few times, I have enjoyed the burgers that I ordered. The amount of fries that I get here is always worth the money, and I love it when it is served all over the inside of the bag that it comes in. Like many of these other places, you can order it bunless, and the burger is still great. The only things I must say about this place is that I always prefer eating my fries with mustard instead of ketchup, and getting mustard for my fries is not instantly as accessible as getting ketchup or vinegar. Also, if one is going here, he or she must be aware of how much money to set aside. Expect to spend around $30 for a nice sized meal for two people. This is always a great place to be in terms of flavor and quality though. read more

If your looking for a greasy burger joint much in the line of "In n Out", then this place is pretty much that. You can pile on all sorts of toppings for free. Fries are kinda flaccid, but the cajun powder seasoning is pretty good. Overall, not bad. read more

I have eatin at Five Guys twice at two different locations. Even though both times i felt like i was having a heart attack from all the grease the food did taste great. The layout of the rest. in Vacaville is not my fave, a little cramped. For the price of the food here i would rather just eat at in-n-out as i can't see spending this much for fast food and paying a la carte for it all. But, i'm sure i will eat here again heart attack or not lol. read more

I must say this place is a lot more better than in-n-out, with the choice of toppings and the actual beef for the burger. Great quantity of cajun fries with a great price too. I just dont like all the peanuts there since im allergic. read more

The burger was very good. Watch out though the "regular" burger on the menu is really a double, the smaller burger is what you'd normally consider regular sized. Do not care for their fries at all. The walls of the restaurant are lined with newspaper clippings proclaiming it as good cheap eats but I think they are overpriced. $10 for a single patty burger, fries and soda. The small fries are $2 and they give you too many. Would rather have half the fries for half the price. If I went back I think I'd skip the fries and just get a burger. But this wouldn't be my first choice burger joint just because of price. read more

Needless to say, we were a bit disappointed. first of all, we were given the wrong burger. The fries are mediocre at best and the burger was just ok. Definitely not an In & Out! read more

I had to see what all the hype was about since I heard this place has the best burgers. The place is a little strange with potato bags and boxes of peanuts forming the lines. The burgers are made to order but pricey and nothing spectacular. Basically an over priced burger. Not what I expected and not someplace I pick to eat at again. read more

Burgers are pretty good. A casual, nice atmosphere. Still prefer In&Out...

I'm writing this review at Kaiser, Vacaville. My Mom and I ate at Five Guys last night. The service was great, which is the first star. I didn't get sick is the second star. My Mom had a cheeseburger and I had a grilled cheese. This was approximately 8:00 pm. By 4:30 am my Mom was not feeling well. Violent vomiting and diarrhea, cramping, pain. She called me at work at 7:50 am. She could barely talk. She called 911 and had to crawl to the door to unlock it. The paramedics found her lying on the floor. The hospital confirmed food poisoning. Needless to say, we do not recommend this place at all. read more

Good ambience for a fast food restaurant. Excellent Burgers for a good price. Tried the cajun-style fries this time but I prefer the "Five Guys"-style ones. read more

Totally not worth the money we paid. Burgers weren't hot. Fell apart on the second bite. Messy and unappealing. Don't know what happened to their "famous" burger, but it definitely wasn't here tonight. Any amount is too much to pay when you get bad food. read more

AMAZING GREASY BURGERS! First thought that always comes to mind when thinking of Five Guys, Burgers of course! I have to say this place puts In N Out to shame! Freshly cooked burgers with a side of a whole bunch of fries! The only down side is the wait time but that is only because you are having freshly cooked burgers, so the wait is just fine! Not to mention the peanuts! I'm glad to see that they finally decided to come to the West Coast! If you have been to this location, you need to go! read more

I still stand on my first review.... The service here sucks.....if you are hungry... And have diabetic old folks with you and small hungry kids... Don't go here... It's a traumatic experience .... read more

My boyfriend was determined to have me say that 5 Guys is better than In and Out. Well.... NOT lol. I love this place but it wasnt "all that." The place has a nice feel but they took forever getting orders out. Id go back and I recommend. read more

Their food is amazing. But I wish they would find a better way to wrap the food. By the time it comes back home. The foil makes it all soggy and makes ppl not want to eat it. It's awesome if you eat in. But take out is bad. read more

Free nuts are cool. Otger than that, its no big deal. Plus, they completely messed up our order. Shoulda checked the bag before leaving, but did not. Was shorted 1 whole burger and messed up the second one. read more

We like the fact that there are a lot of free toppings to choose from to add to your burger. I usually order the little hamburger (1 patty) but if I'm super hungry, I'll get the hamburger (2 patty) which will barely fit in my mouth. They also give you lots of fries. read more

You have to be in the mood for this burger! Better than In N Out. Joint is over populated with tables and chairs a little hard to get around. read more

OK Burgers, a little bland for the hype and price. In and Out has just a little better for cheaper.

Geez, how could an 'effin burger meal create so much gripe? The bun broke apart after two bites. The cheese was no better the neon orange slice on a big mac and saltier than sucking on kelp. The meat was overworked - it fell apart and didn't taste particularly fresh. The fries tasted like cooking oil, and had no salt added. Two bucks for a medium fountain soda. And for the privilege of a crappy meal, you get to pay them twelve bucks. For the same price, I had a perfectly respectable burger plate at Cheesecake Factory yesterday. A hamburger shouldn't annoy you, but five ripoff guys found a way. read more

Why are the meals soo expensive? I paid $15 for a cheese burger medium fri's and a medium soda. I can get the same thing all in one for $5 anywhere else. Yes the meal was good but not the price. I don't think that I will be going back. read more

Not a big fan of the food but I want to just base It off my preference . Love the peanut set up! The peanuts are entertaining and make the wait time on the food worth while. read more

I would'v'e gave 5 stars but it's pricey for a regular bacon cheeseburger, small cajun fries and a small soda. Also, the fries became soggy since I took it to go. Other than that, I finshed the 2-patty burger pretty fast and it tasted great! The cajun fries were different, but good. I'd go here once in awhile. read more

Best burger joint in California hands down. I would suggest this restaurant to any and everyone

After dropping a friend off @ the mall, we ended up here and were pleasantly surprised .One word : delicious ! Great service and way better burgers than in&out that's for sure. read more

Stopped in yesterday for a quick bite and to see if you could get a "Paleo" style burger, ie., no bun. They do indeed have such an item you can either have it in a bowl or wrapped in lettuce leaves. We chose the bowl with just about everything. The burgers arrived hot and the toppings as ordered. I was disappointed that a single patty was so small. It was a bit too well done for my taste, but food safety has to trump personal preference in fast food setting. All in all a good burger with good flavor, but my preference is still In n Out by far. read more

One of the best, if not the best in Vacaville. I know its a chain, but the food is consistent, the burgers are awesome and the fries...well, they are terrific! The ability to put on all fixings you want and as much as you need is fantastic. The idea of peanuts to snack on while waiting is another creative idea for a burger joint. We are definite regulars and for now, don't go anywhere else in Vacaville. read more

For me the meat was outstanding, many addons but I know its just another burger joint.
