This is a five star diner. Service was excellent, quick on the refills, super nice staff. Decor was awesome, exactly what you would expect from a 24/7 diner! *cash only, can get busy* Came here with friends for breakfast are a few days at Shenandoah. It was exactly what we needed. The group got the #4 and the #3. The #4 was huge, tons of food, great price, really enjoyed the home fries, massive pancakes, and solid French toast. The #3 didn't quite live up to the #4 but it was more manageable. The omelet was solid, overall it was solid. read more

I absolutely love this place. It has the most homey feel and the staff are always so nice! My family has gone here for years and I'm sure will continue! Great food as well! read more

No matter how run down the place is you will still enjoy the atmosphere at Frost Diner. It can be hard to get seating if your party is more than 2 people during any normal eating time: breakfast, lunch, dinner. The seats and tables are in bad shape. The restrooms are in worse shape, doors don't close etc. The jukeboxes that use to be on every booth table are gone :( Cash only, but there is an ATM that will charge you a few dollars to use. The food is plentiful, cheap and what you'd expect from a diner. For all it's faults this is still a very neat place to visit. read more

Pretty much your average American Diner. The Frost Diner consistently wins "Best of" awards in town so that tells you something. There is absolutely nothing special about the food - it's diner grub. Inexpensive with decent portion sizes. Service was adequate during the breakfast rush. Yes, the inside is showing some wear and could use some freshening up. I came upon this realization while sitting down in the booth - I sunk so low that the table was chest high. I think next time I'll take a counter stool :-) If I'm in the mood for diner food - the Frost Diner is where I'll head. read more

After living in Warrenton for ten years - and elsewhere in Fauquier for many more before that - the wife and I finally got around to trying this place for breakfast. The ambience is right out of the 1950's and early 1960's, now thankfully without the accompanying cigarette smoke. If you're old enough to remember those days you should definitely stop in and check it out. If you're not, go watch some Happy Days reruns to get acclimated, then stop by here. I had the ham and cheese omelet, with grits and wheat toast. The omelet was made with three large eggs mixed up with lots of diced ham, and stuffed with American cheese. Grits were OK - not too much can go wrong there as long as they are cooked long enough (they were.) With two slices of toast, I couldn't quite finish it all. The coffee was your basic Maxwell house or equivalent. The wife had French toast with bacon, she said it was delicious. The waitresses this morning were not overly friendly, but not particularly grouchy either. I'm fine with that, we just wanted a good breakfast at a fair price, and that's what we got. No complaints here. read more

Cash only... with over priced atm out fron. DIRTY HOLE.... LIKE WOW THIS PLACE IS DIRTY. Air conditioning broke. Looks like nothing has been cleaned in years....... smells like ancient fryer grease. My initial thoughtbis if you cant clean and fix your building..... what kind of corners do you cut on food safety.. I just walkex out. I didnt order. Best thing that can happen is that this place burns down.. read more

Excellent service and food! Delicious and fresh breakfast! Loved the blueberry pancakes!!!!

Like any greasy spoon diner, Frost Diner shines for breakfast, but other meals are uninspiring. They do have a smoking section, but if you sit on the other end of the counter, it's not noticeable. The hash omelette is my standard fare, and the home fries make it worth the trip. They cooks are good at special orders - things like extra-crispy bacon or eggs over hard come out as desired, and really quickly. I usually order the same items, and often my check varies by about 50 cents, but I look at that as charm, not so much as something worth complaining about. Not a great place to take the kids (at least not our 3) since it's usually crowded during usual breakfast hours, and the small booths are first-come-first serve seat yourself deals. There really isn't a waiting area, so it's awkward to stand around with the family watching other people eat and mentally hurrying them up. Sadly, this IS a diner, so if you're dieting, you are pretty much S.O.L. (They do offer eggbeater omelettes, however) read more

My fiance lives in Warrenton and suggested that we check out this spot because we wanted breakfast for dinner. We came yesterday when it was about 100 degrees out...I'm not sure if their a/c was broken or if it just doesn't work well. But we sat down, were immediately served drinks by a really nice waitress, looked at the menu, but just had to get the heck out of there because it was just as hot inside as it was outside. I felt really bad leaving because I would never usually do that, but we were sweating. The menu looked really good though, so we're definitely going to try to come back soon...maybe in the fall when it's not so hot haha. read more

The parking lot was only half full on Saturday so we decided to stop in. Kids walked in and grabbed the stools at the counter. Friendly waitress gave us menus and took our drink orders. Total food order was 2 bacon cheeseburgers with fries platters and a french toast with scrambled eggs and 4 bacon strips. (i think it was 4) First. Except for my own burgers, I don't think I have ever had a better one than at Frost! Absolutely how I like it. My daughter confirmed! I don't normally eat French toast because it is too much bread. My son had me try his...It melted in my mouth! Seriously. My son even ate the "crust" lol. The girls were constantly moving. Cleaning, serving, comunicating to the cook and the prep team in the back, checking on everyone. Usually, at any other resturant on any given day they are standing around talking to each other. No time here. We saw the cook clean his stove top at least 5 times while we were there..No kidding! Nice! The orders he lined up looked so good. We can't wait to go back. * Delicious* Thanks Frost! read more

Shout out to Amy for being beyond hospitable as I just got off a 13 hour shift. I was pleasantly surprised at the small crowd in the Diner at 11 P.M. Thursday night. Amy was tackling down any task thrown at her with a can-do attitude! I've been coming here a lot more recently because it's 24-7 always fast and priced fairly well! What puts this place over IHOP or Dennys? That homing feel, come for the grub stay for the staff! Keep it up guys! Side note- Get the fried mushrooms and thank me later read more

A little hit or miss but the no frills breakfast is by far my favorite in town. Great place for a quick bite and when you order eggs over easy, they are perfect! read more

Stopped by here today to grab some breakfast. It was a busy Sunday morning but didn't have to wait for a seat. We took a booth in the back corner. Ordered French toast with home fries and coffee.It took nearly 40min to get our food. When it came out, the French toast wasnt cooked thoroughly and the home fries were a bit undercooked. The only thing g enjoyable about this experience was the sub-par coffee. Would not recommend to a friend nor will I return. read more

We have been eating here for over 20 years. Yummy food, and a wonderful staff. Very good breakfast, and a great place for a midnight snack.

Someone said this restaurant was closed but I called and they are still open for business! I can't really rate it as I've not been there but didn't want people to think it was closed. Looks like a great place! read more

An adorable, classic diner with friendly waitress and good food. Now that you are no longer able to smoke in it, that reduced the about of people that come to eat there. It saddens me to see this diner go downhill because of this new law. They have the best hamburgers, pancakes, milkshakes, cakes, salads, grilled sandwiches, waffles, hashbrowns, etc. I go once a week and can't get enough! read more

Supposed to be a sister diner of the Tastee Diner (or 29 Diner) in Fairfax so this is what I will compare it to. I have been to this place many times now. Every single time I have walked away unimpressed and almost angry. If you go in late at night, no matter what you look like you will be treated as if you are a criminal. I am not going to dine and ditch, I would just like my coffee and food please. One morning I came during a rainstorm and sat in the booth in the far right back and it was leaking onto the table (and in our food), when I told the waitress after we moved she didn't seem to care at all. I hate to say it, but I'd rather have IHOP??? Wow. That is painful. read more

Stopped in from out of town while on a trip. We came on a Sunday morning around 10am for brunch and waited nearly an hour for breakfast food. The meal was fine, average diner food, although I did have a hair in my toast. As I was checking out, the waitress ringing me up asked how everything was. I answered honestly that we waited a long time for our food. She responded with "well, we're busy, that comes with the territory." I was disappointed by her blasé response. I understand this is a local establishment, but an hour for eggs and toast is unacceptable and an unsympathetic reaction to the poor service is even worse. read more

Solid greasy spoon place. Burgers and breakfast. Small and cramped. Very dated. But those are what makes it charming. Its a throwback. It's been as it is for decades and it provides a needed all night food spot. read more

Love the atmosphere. I am new to the area and this is one of the first places I have eaten. I will definitely be back

In the style of the old railroad car diners, Frost diner is a wonderful and refreshing blast from the past. Good food, made to order, and easy on the wallet. Can get busy in the morning. Try lunch and dinner as well. Cash only but there is an ATM. read more

One caution about Frost Diner. They are open 24 hours a day BUT you can't get all the food 24 hours a day. That is deceptive to me anyway. You would think if they are open 24 hours a day you could get all their food 24 hours a day. My waiter said "They have to clean up sometime". I asked him what the REAL hours are and he told me from 6 am to 12 pm. Otherwise you come to find the fryer being cleaned, the gravy thrown out, etc. But when they are cooking I sure do enjoy the food. Usually I order a hamburger steak with gravy with onions on top of the hamburger and a double order of fried with regular gravy on them (no onions). It was more than I could eat. I finally quit eating it so that I had enough room for some of their cherry pie with ice cream. Oh yes, cash only, no credit cards or checks. They do have an ATM machine. read more

Went here for breakfast this morning. I ordered the Maria Special. Scrambled eggs, ham and home fires. It tasted so off to me that I really only had a few bites. Everything had this weird sour flavor. Well sure enough about five hours after I'm violently ill. Definitely food poisoning. Don't risk it. read more

Stopped here to eat last night as a treat for my sons last day of school. He loves their milkshakes and this out of anywhere local is where he chose. I had the french toast, eggs and bacon. French toast was slimy in the middle, and the bacon was over cooked. So I ate just the two scrambled eggs (at least they were good). My son had a milkshake, which was good, and onion rings they were NASTY! Looked and tasted horrible. They were over cooked, burnt and tasted like the grease had not been changed in forever. I can't believe a cook would even send them out or a waitress would serve them. Then to top it off: They had a special 3 french toast and three eggs and meat, but I couldn't eat all that so when ordering I asked for only 2 of each, as I looked over the menu to see if there may have been a option with less food, the waitress said, "don't worry I will adjust the price" and that she did! Silly me I assumed it would have been cheaper but no it cost me more by a few dollars. NEVER EVER AGAIN WILL I EAT HERE!!!! I am sure there are plenty of other places in town that serve good milkshakes. So basically I paid $23 for a milkshake and 2 eggs. read more

Interesting stop on the way to PA. Food was awesome but the service was questionable. They were also out of a lot of things on the menu. Kind of weird locals place. read more

Walked in with the hubby and waited to be seated. Four employees saw that we were waiting for quite a bit, and even passed us several times without even a nod of acknowledgement. Three of them stood right in front of us at the register and acted as if we didn't even exist. We walked out to go to a real restaurant. I'll highly recommend people to avoid this place when coming to visit us in Warrenton. read more

First visit will likely be our last. Noticed after drinking my water that there was something in it. It was on the bottom and looked like old squash seed. It was blackened. I assume it fell in their ice? Anyway, I pointed it out to the waitress who didn't say anything and just took away the water and brought another. I expected at least an apology just to show concern. We ordered a turkey sandwich with mashed potatoes and a porkchop with eggs over hard and a biscuit. The sandwich came out first and there was a long wait for the porkchop. They should have held off on serving the sandwich so that both dishes would have been served together. The turkey sandwich was blah with boxed mashed potatoes. The porkchop was greasy, salty and dry. The eggs were overfried and browned and the biscuit tasted like it came from a mix. We both have had better diner food although this may be the best you will find in Warrenton? We were cold sitting along the windows with drafts coming in from outside. I had to go get a jacket and blanket from the car. read more

Great breakfast, the place was packed. Once I sat down, I saw scrapple.... oooh yes !! so I got the 2 eggs,scrapple and French toast. Scrapple hit the spot but the French toast was awesome, hot hard not overly done perfect. read more

Diner food. CASH ONLY. Cheap prices. Nothing special. I had the pork chops and found them a little disappointing. The wife and kiddo enjoyed their breakfast food even though it was mid-afternoon. I might go back again, but it is not on my to-do list. The service was fine: not over the top, but we were not neglected. Three stars instead of two because the prices were reasonable. read more

The food was very good here for breakfast. The portions were large perhaps larger than we needed, and the price was fair. The seating was a bit cramped but the service was fast and pleasant. read more

Great little place that the locals all have known about for a long time. I had driven by for 2 years and never went in. Prices are toward the high end of $ for breakfast but nothing at IHOP is as good as this place. Friendly service, cash only. Hash was real homemade hash.Omelete was good. French fries are store bought. They could probably use better bread for toast. Other than that, its a great local place. I will go back and try it out for lunch sometime. Oh, and its very clean, which sometimes older places have troubles with maintaining. read more

At first it seemed nice, then the waitress grabbed our food with her bare hands. We left as soon as we saw that, lost of appetite. Will not be going back. read more

This is the real deal when it comes to diners. Sometimes you just want a "real" breakfast, no frills, or some comfort food late at night. This place delivers. It's not fancy, it's not even noteworthy food...but it IS fresh, hot, filling, satisfying. All your breakfast favorites, and then some. I've only been for breakfast, but they have an extensive grill menu and I can imagine this would be a great place for your late night munchies as well. It's good to see the fern bars and chains are still leaving room for a bit of Americana. read more

We stopped by this place on the way back from hiking in the Shenandoah Valley. I am giving this place three stars because the diner itself is tiny and could use some renovations. Also, the diner is CASH ONLY and there is no signage that points this out to patrons. The way I found out is by looking at other YELP reviews. The food was good, portions are adequate, and the prices are reasonable. It's the 21st century and the restaurant could probably get more customers from accepting credit cards. This increased revenue despite additional fees from VISA, Mastercard, etc. might help fund a renovation or expansion of the place. read more

Love these old-school diners. Had a fine breakfast here last week. Let's hope this place sticks around another 50+ years.

Great food. Eggs were amazing. Sausage was amazing. Hash brown patties were amazing. No wait time on a Saturday. Toast were perfectly toasted and perfectly buttered. read more

We popped in on a very busy Sunday, so it took a while to get seated. The food was good! My husband said that the pancakes were some of the best he's had! Great breakfast spot! read more

Love this place 24/7, but bring cash! Dive diner with good food and good service. Strongly recommend!

They should light this place a bit more--I thought for sure it was closed when I pulled into the parking lot. But it was open, and I'm glad I made the effort. The fried chicken was excellent. Everything on my plate was fresh and served promptly. The Frost Diner is about as old-school as it gets--I liked the decor and the people, but the food has to meet the mark, and on my visit, it certainly did. read more

Moved here recently, and saw it on a list of "must try" when in Warrenton. Staff was friendly, but food was poor quality. My Dad had fried shrimp w green beans and fries. Everything was frozen or canned; nothing fresh. The shrimp were fried to a dark crisp and super-tiny; the fries tasted dried out, and the green beans were almost mushy. Looked gross. I had a burger that tasted good, but again, fries were dried out and not the least bit fresh. Maybe we caught it on a bad night, but it did make me wonder why the diner is listed as a "must try" as it was not good, and I would not recommend it. read more
