I honestly love this place. The first time I came here I was told the green sauce will get you hooked. Every time I get here I think about this because I ask for a minimum of 3. I love love love this sauce with all the food. I come here with my coworkers or as a date a very versatile space. Please get either the sweet potato fries or the onion rings or the garlic fries

Great place to get a milkshake after school in Menlo Park. Jefferies has been around for many years, and always dependable for a good old fashioned shake and cheese burger

I like the ambient here. The service is good. The burgers are juicy and tasty. The medium is a bit redder than I would expect. The medium-well done is a bit too cooked. The bread is soft and the veggies are fresh. The onion rings and the sweet potatoes are soft and crispy (a bit oily). The Caesar salad is ok - a bit weird. It has some oily dressing on it with a side of Caesar dressing. I like the root beer float and the chocolate shakes. Overall good experience and I recommend it.

Love this place! Great burgers! This is my favorite burger joint. Big juicy burger patties, perfectly soft bun. Excellent French fries too. Love the pickle spears too! The service is great even when it's crowded. Lots of roomy seating whether you are a small group or big!

I especially like their signature salad with chicken. It's always fresh and very tasty. Their burgers are normal burgers, exactly as expected. The fries are plentiful.

I moved to this area years ago and always drove by Jeffrey's on my drives down El Camino, but never found a reason or opportunity to try this spot out. Recently though I decided to take my toddler out for a little Mommy & Me date and since we needed to run a Trader Joe's errand, we found the nearest playground at Burgess Park to play at before looking for a fun toddler-friendly dining establishment. This is how we chanced upon Jeffrey's as an option on my Yelp search. There's a decent, medium sized lot behind the restaurant. Bonus is that it's right next to the CalTrain tracks, and there's a bit of a clearing between the bushes for a toddler-sized train fanatic to see all the trains whiz by. The lot was also filled with some pretty awesome cars (it ranged between classic cars to even a Porsche Boxster and a Lambo) that a toddler-sized car fanatic enjoyed (well okay, he's easily impressed, but so am I). It's a typical canonical diner with the iconic red booths and menu offerings. The place feels extremely inviting. I can also attest that the bathroom is very clean and spacious (tiny toddler bladders and icky hands). The dining area is similarly spotless and extremely spacious with lots of tables and booths to choose from. I was pleasantly surprised and pleased to see that the booths are in pretty pristine condition. I'm used to seeing some other establishments with cracks in the cushions or duct taped over, so this definitely added to the awesome factor. When you first enter, you see a counter under the menu boards with multiple attendants to take your order up front. Our person was very friendly, helpful, and patient. He was also very helpful when we first ordered a chocolate milkshake, and then we realized afterwards that a milk was included with the kid's meal. Since the kiddo picked chocolate milk, the attendant inquired if we still wanted the chocolate milkshake given the similar overlap. And while we specifically came for the treat, I genuinely appreciate checking that with us first. The only bummer to the interaction was that later looking at the receipt, we were charged for the chocolate milk, so maybe I misunderstood the menu and a milk is not included with the kid's meal? Altogether, we had ordered: 1) Burger bowl w/ cheese, 2) Single order of fries, 3) Kid's cheeseburger + milk + apples, 4) Chocolate milkshake, and 5) Soda cup. My 3 year old was able to inhale half his decently sized burger (it's a kid's meal but it's not any smaller than what a grownup would get), so it is picky kid-approved! My burger in my bowl was perfectly cooked to medium, and was a delicious slightly lighter version of getting my burger fix (only slightly lighter given the heaping pile of fried onions up top). The greens were incredibly fresh, not a single wilted lettuce leaf in sight. All in all, Jeffrey's is now on our family's radar as a great place to take the kids for a fun meal out, and I'm glad it is not just a pin on my Yelp wish-list any longer.

Best burger place. Been going here since 2016. Classic diner, polite staff and crowd. The fries and onion rings (get ranch) are fried to perfection and the oil is changed out far more than regular burger restaurants. They use a high quality oil that doesn't flare up my acid-reflux if I were to eat other fried food spots. Just as with any proper restaurant that caters to a general crowd (older and younger people), don't be afraid to add some salt onto everything. I always get the bacon cheeseburger and sometimes I add onion strings on top of the regular onions or mushrooms. The soda machine is maintained and cleaned much more often. I crave a fresh, sparkling Coca Cola so bad here, but their milkshakes are delicious. I've worked in a kitchen, and I recognize that what they have called is called effort and determination, because it takes constant effort and determination to do extra work for the customer on a daily basis. This is why I have been going here since 2016. Because instead of triple frying and using large amounts of oil myself, I can go somewhere that I feel takes care of me how I take care of myself at home. No corners cut.

It's a cute diner spot to enjoy a bite at. Their servings are huge. Definitely recommend sharing a meal if you don't have a big appetite. Burgers were juicy, fries were lightly crisp and the shakes were a good sweet treat. We shared a shake and asked to split it into 2 cups and it was still too much. It was definitely hard to finish lol Definitely recommend trying this place out!

Diner Food we can here for lunch with my colleagues on a Friday and the line was to the door! Jeffrey's does a great business. Ordered and paid at the cashiers ! Got the mushroom burger bowl and it was yummy . Colleagues got speciality salad, bacon cheeseburger and chili cheese fries . Everything was amazing ! Beef was fresh and high quality and the mushrooms were bomb.com. Can't wait to come back ! Bonus is there is lots of seating and parking .

We were able to walk right in. It felt just like a 50s diner. Impressed at the cleanliness. The food was delicious, and the portions were fair. Service is fast and courteous. Try this place if you don't want to be nickel and dimed at the Palo Alto Creamery. Better food, better parking, friendlier service, larger restaurant...how have I not found this place before?
