Food and service nice! fast service. Nice hosts and the ambiance. Close to home and children friendly food. read more

It's backed into hell. The food tastes stale and flavorless. This because most the food on the menu is pre frozen then re-heated in an oven. Even the waffles are from frozen. High prices but poor quality. read more

Denny's - Salted Caramel pancakes. Really good. - Breakfast & Brunch Near Me - Simi Valley, California

Horrible Food! 6/26/26 at 5am, I purposefully have avoided going to any and all Denny's for a number of years because the food has been awful at all locations. I and my son had just spent 6 hours at an ER and we were very hungry and tired and unfortunately the only place open at 5am was Denny's in Simi Valley at 5am. So I called in for a to go order and picked it up to take home! First I specifically asked for no bell peppers in my omelet and yet there were bell peppers in it and the potatoes looked and tasted like they were days old and were inedible. The sausages also inedible my son said they tasted like dog food!!! Gross!! read more

Excellent service! Karla and Maria are awesome! The food is always great and the place is always clean! My go to spot!

I have been to a lot of Denny's and this one was by far the most clean and had the best food. The host Noemi (spelling?) was super nice and led us to our table with a smile. Then our serves Moses certainly parted the red seas for an incredible breakfast experience. I don't live close to the area but would definitely come back and recommend the Fit Fare Slam . I asked if anything changed since our last visit (for Easter with family) and apparently theres a new manager now. Things were just great read more

This is the best Dennys ever! Great friendly staff and wonderful food! Count on me coming back.

They have such a great staff here, and are always hustling! The food is classic Denny's. You know what you're getting and it's always solid. Royce is a kind server who always treats us well, and is welcoming. Luis deserves a shout out too for being on top of things. We're glad to have a Denny's back in Simi. read more

Such a great place! I always stop there because I really like the service and Silvia, the manager, transformed this place 180 degrees! The food is great, the staff is great, clean, nice atmosphere! My family loves it! Best food ever!!! read more

Alejandra is an amazing server with excellent service. She had multiple tables by herself and attended to each one with great time!

There was only one waiter didn't come back for refills. Extremely bad service. The food was okay could have been warmer.

I see on TV that they have a value menu. But they don't bring it to your table when they seat you. I had to get up and ask for it. I wouldn't eat there if they didn't have that menu because there prices are very high on everything else. Ridiculous read more

Had a fantastic family dinner at this Denny's! The restaurant was spotless, the service was fast and genuinely friendly, and the food really stood out compared to other locations. A special thank you to Misty for providing such excellent service and making our experience even more enjoyable. Very enjoyable ambiance. read more

You can never go wrong on Dennys, distinctly and uniquely American, inside and out. Breakfast combos are always the best deals, pancake and sausage, eggs and bacon. Arabica coffee at its best and a smiling and happy server is always around to serve you their best foods. Their slice of steak is not the best but more than enough to satisfy your cravings for supper or lunch. Parking is abundant, neighborhood is safe, and pricing is moderate to average. Food is excellent and dessert line up is not too bad. read more

It so easy to go here . Food is always good . If you sit in the center booths they don't have any air ducts over them so it's more comfortable . The Slams getting creative but i do remember the days of the 1.99 grand slam breakfast served 24/7. Now that we are in our golden years we are taking advantage of our senior discount the 55+ menu is decent when the hubby wants breakfast for dinner . Karla was our server and we wanted for nothing . She was terrific! read more

WELCOME BACK to another RESTAURANT REVIEW !! (cheers in the background woooo!!) okay so today we went to eat at Dennys for jadical radical's 13th birthday. We entered and automatically we wanted to use the claw machine. we put in a dollar, and the claw machine didn't even TRY. It opened up its claws, closed them, and bam we lost our chance. Okay whatever. we ordered our food the waitress was super cool. the rad jad ordered the berry vanilla crepe breakfast, w/o cream. When he received his order, the crepe was SO SMALL. like super super tiny, à baby would've asked for more I got the cali club, it was so fire We also got the brownie sundae with oreo pieces. very yummy, but be warned, it's VERY sweet so be sure you have someone to share it with the place looks very nice too, tjey have a cool simi valley sign. also, weird thing that happened bht they gave us a water that was literally pink.. it tasted weird too so, uh, ya. but it's okay! food was overall yummy read more

Ugh!! So Simi Valley has disappointed me from the hotels to now Dennys. I had a simple order to be delivered to my hotel, in town from San Diego. Our food was literally down the street. The order was thrown in the bag and boxes. 1 Grand Slam looked like a kids plate. I did not receive my fruit, nor my orange juice or bottled water. The cinnamon pancake puppies where just puppies. 5 of them. We recieved 2 sryups, for the pancakes. I asked for 4. I was so disappointed. I called and the young lady was nice offering her apologies for the mistakes and to refund me for the water and juice. The food was not even warm, and the restaurant is down the street. read more

The service was great and they lowered their prices. Not to mention I think they're open 24 hours.

Denny's is almost always a safe bet when you need to feed a small group in a hurry. The food is safe, the service is acceptable, and the joint is clean enough for the most part. It's comfort food heaven for the senior crowd. Good tea. Good coffee and free refills on pop or tea and coffee. What could go wrong? read more

For a place that's 24/7 I tried to place an order and it wasn't letting me even though they advertised they were open on the app and online. I then called to hear the place was closed from an automated number. Another inconsistent experience from this "24/7" mess of an under employed Dennys read more

Yuppp! This is definitely the nicest, cleanest, Denny's in the area! Our server this time was so nice! The first time we came here they were understaffed but now I think they got it down! The Food was great! Tasted amazing and we were very happy! Best Denny's! Lots of parking and inside is very clean and new still! read more

THANKYOU. read more

On 6/5/25 Maria M was our server. It was super busy with graduation breakfasts in the restaurant. Maria provided amazing service to me and my daughter and went above and beyond in taking care of us, even when a computer glitch erased all orders when it came time to pay. She patiently and accurately re did the orders and always attended to our needs during the meal. The food quality was fantastic and her service and smile was amazing! To the manager- please recognize Maria M for her dedication and make her employee of the month. She is amazing. W read more

This place needs better workers no professional people there at all they just hang out and talk with each other terrible service I just don't understand read more

Waitress Maritza is thee best! She k les my order every time-she never forgets the onions!

There was a Denny's in Simi Valley for many years, and then there wasn't one for some period of time. Then they built a new one on the other side of town from where we live. Dear Hubby stopped by there while running errands to pick me up a BLT. Since I don't eat dairy (oh how I miss real cheese!) any longer, BLT sandwiches are one of the things I can half that aren't inherently lacking from not having cheese. Well, his first statement as he hands me the bag with my sandwich and fries is, "That's the last time I'm ordering you a BLT (From here, or anywhere? It's been a touch search for a good local option!). He tells me to look at the bill. $19.83 with tip. For a BLT??!! Unbelievable. Turns out, that as "America's Diner" they don't have BLT's on their menu. They didn't tell my husband this, and instead ginned one up off their Super Bird. The Super Bird has turkey, cheese, and bacon on sourdough. So they leave off the turkey (didn't ask him if that was desired), leave off the cheese as he requested, leave off mayo, even though he asked for it, AND charge $2.10 extra for the bacon. They did tell him their would be a charge for extra bacon, but didn't take into account that he wasn't receiving turkey or cheese. I'd say that they came out on the better end of that financial transaction. Although, they've likely lost us as customers until a long time passes and we forget how they cheated on the bill. Pennywise and pound foolish, as they say. Our last experience at a Denny's was almost a year ago in Camarillo and that wasn't great shakes, either. I'm thinking that the chain may be going downhill and into a permanent decline from which there might not be a recovery. The fries that came with the sandwich were very good; the best thing in the container. On the BLT, without the mayo, the total flavor package was lacking. Mayo and tomatoes - mmm normally, right? The bacon (for which we paid extra) was much saltier than it should have been. The lettuce was floppy - not old, but just lacking in body and crispness. The tomato had very little flavor of its own. One small positive note - the French's ketchup packets provided with the to-go sandwich do not have high fructose corn syrup. That's a plus! They do contain a small amount of regular sugar, but that seems to be preferable to HFCS in so many other fast food condiments. Definitely not worth the price paid. I'm quite disappointed, actually. I get that there's a delicate balance these days between restaurants being able to pay enough to get/retain help, and the prices they have to charge. For consumers, though, the cost of eating out seems to be skyrocketing, and the quality / satisfaction / overall experience is often not measuring up with what we're expected to pay come time to settle up. Big sigh! read more
