“I highly recommend this Denny’s! The entire team here is wonderful always so kind, welcoming, and professional. The restaurant is consistently clean, comfortable, and inviting. Our favorite server, Irene, goes above and beyond every visit! She’s quick to seat us, always greets us with a smile, and gives the best menu recommendations. We love coming here every Sunday it truly feels like our home away from home!“

“The bread was incredible and I was sold from the very first bite. The bacon tasted freshly made and the eggs were cooked just right. The hashbrowns were crisp with a rich buttery flavor that made the whole plate unforgettable. I cannot believe I kept passing this place without stopping. It has officially become my favorite spot for breakfast.“

“Been to countless Denny’s locations in my life but this would be one of my more memorable ones. The location was moderately busy but that didn’t stop the staff from providing top notch service. Everyone seemed to be getting served and tended to in a timely manner and I saw our server get multiple thanks and kudos from departing guests. My wife is a bit picky on food and she had the pot roast. She said it was very flavorful and moist (she even packed her leftovers to go which she only does when she’s genuinely happy with her food). She also ordered a side of zucchini and squash (oh no…) and said the only place she’s had better is mine at home (only because practice makes perfect LOL) or a pricey steakhouse we go to on occasion. I had the Lumberjack slam and when I tell you every single component was perfect, I mean perfect. Perfectly cooked meats, perfect over medium eggs, and heavenly hash browns. I upgraded to cinnamon roll pancakes and don’t regret it one single bit. Fluffy and light, perfect amounts of salty butter, cinnamon, and glaze. It was like a Cinnabon on steroids 😆. I sincerely hope this is the norm because if it is, I may have just found my new go-to diner when I need a great meal.“

“Anyone that works the night shift is a special kind of champion. Not all heroes wear capes. Thanks, Earl! You're the best!“

“This Server like most of the servers and the restaurant say hi to you and asks how you are doing then ask for your beverage and if you are ready they will take your order Ninfa. Is very friendly and courteous she usually waits on me and my family when we come in together but on top of everything around her she is a very good server. Thank you Ninfa.“

“Richie’s Diner is one of those spots that reminds you why the good old-fashioned family diner will always beat the trendy places. Every time I walk in, the staff treats you like you’ve been part of their family for years — genuinely friendly, always attentive, and never rushing you. That kind of service is rare these days, but they still do it the way it’s always been done: with pride and heart.

The food? Man, it hits the table fresh, hot, and full of flavor every single visit. Whether it’s breakfast, a classic sandwich, or one of their big comfort-food plates, you can tell they care about doing things right. Portions are generous, recipes feel traditional, and everything tastes like it came from a real kitchen, not a corporate playbook.

Richie’s is exactly what a family-style diner should be — warm, honest, and consistent. It’s the kind of place where everyone smiles at you, remembers your face, and makes you glad you stopped by. Highly recommended.“

“I grew up in chino and have never tried Toms until now, let me tell you how much I’ve missed out on!
Once you walk in you are greeted with such a warm friendly aura. I got the bacon cheeseburger and I fell in love, they have such fresh ingredients and amazing taste! The fries are crisp and the ranch is to die for! I got my order in a quick manner as well! The staff is very attentive and friendly, everyone gives a family vibe I truly felt at home and comfortable! Since christmas is around the corner they decorated so cute as well with life sized santa and star wars. 10/10 definitely recommend for some tasty, juicy old fashioned burgers!!:)“

“i was greeted by a guy who goes by "superman" he was absolutely awesome my card was acting up which was frustrating because i had money on it , he paid for my desert and asked me to pay it forward even though i was wildly embarrassed i am thankful for the act of kindness !!!!“

“Patty was excellent and got our food to the table hot.“

“I have known about Nancy‘s for quite some time because it is one of the famous diners that are dotted along former Route 66. There are many in the area and I would say that Nancy May’s is one of the better ones. We stopped in for our first time this past weekend and had a really nice experience. It was our server’s first day on the job and she was extremely sweet and did a great job and so did the kitchen. Everything that we ordered came out very fast and just as we requested. It’s in a small shopping center so there is plenty of free parking right in front. They don’t have any outdoor seating and inside is pretty small but in a cozy way.

For our first visit, we wanted to start with some of their bakery items so we chose the Cinnamon Roll and the Coffee Cake. They were pretty good, but you could tell they were not homemade and were very cakey. The store bought pastries never seem to be as good as homemade to me. This was not my favorite part of the meal. For my breakfast, I chose the Country Fried Steak and thought it was fantastic. It was not overly cooked and the eggs were done perfectly, I was a big fan of the dish overall. I would definitely recommend this place to anyone searching for a great diner or to anyone looking for a casual breakfast or lunch option.“

“Tonight we order the family cheeseburger feast. Seriously AMAZING. They toast the buns and put them in their own container. The grill the burgers, melt the cheese, again separate container. Then...the fresh fixings, lettuce, pickles, fresh tomato slices, pickles galore, white and red onion slice. Phenomenal! Did I mention the fries? Guess what? Separate container. We fed our family of four and still have leftovers. I am renaming this. Build a burger. Everyone’s burger was unique, custom and we were all satisfied.“

“The service was great and fast! Very friendly and food was very good! Very friendly service!!!“

“Well, food is excellent, I was there for breakfast, was my first time there. The choices were great, I ordered from a specials menu… delicious, I had one scrambled egg, cooked to perfection, hash browns, sausage… all very good. I was there with a couple of friends, they each got omelets. Service wad quick, and friendly. Very attentive. Great music from the 1959’s… it was playing in the background. I will return, truly enjoyed everything.“
