We love this place. The staff are very friendly and professional. Prices are reasonable. Our favorite waitress is back so we are happy about that. The food is always delicious. And even when they are super busy, you never wait too long.

As soon as I walked in, I was greeted with a friendly smile and a cup of coffee. It has that local 50s 60s vibe. The aesthetic was local pride trophies hanging on the wall local landscape art mural. The breakfast was good. I had French toast, egg, and bacon definitely a place. I will come back to visit.

All was good except the cook on the “poached” eggs. They were actually a perfect hard boiled. Too busy in the restaurant to be asked how the food was even though I specifically left the eggs visible with their solid gold yolks showing. Would have been nice to at least have it acknowledged. Especially considering the kitchen sink omellet is one of if not the most expensive breakfast item on the menu. Disappointed.

Best beacon cheese got dog ive ever had! The burger made it clear many visits would necessary. I’ve heard about Lumpy’s for years but yesterday was my first visit. It was well worth it, not too mention affordable as well!

A classic American diner experience! I was craving eggs Benedict and their Kitchen Sink Benedict was worth the extra $2. The eggs were poached nicely and the sauteed veggies and extra meats added a lot of flavor and texture to the dish. Great staff and overall vibe as well.

We LOVE Lumpy’s! The milk shakes are incredible, and there are a ton of flavor choices. Husband and I like there almond Rocha shake. They offer about a dozen different types of fries. For dinner, I really like the French dip. The meat is very tender and the au jus has a lot of flavor. This past visit, we tried the fricks for the first time. Kids weren’t into them, but I loved them. Husband usually gets the rockabilly wrap. Last night he tried the piggly wiggly and added BBQ sauce. He loved it. The staff is always super friendly. We have also eaten breakfast at Lumpy’s, and it was just as good as lunch and dinner.

What a great place. Food is good and the wait staff terrific. The cafe/restaurant is not that large but does have both indoor and outdoor seating. Parking on the street outside is plentiful and free.

10/17 @ 7:20am. Not crowded. That 10oz ribeye looks like 8oz. Needs salt and pepper, very bland. Pork chop was seasoned and tasted juicy. Large menu decision. Only diner opened at 7am. Coffee is robust.

Great atmosphere to take the kids. So much going on in the place. The price was just right and it seems like a great local hangout. The staff was super nice and the wait was not long at all. Must have chili cheese fries.

I just love going to Lumpy’s Diner! The servers are simply phenomenal, kind, generous, engaging, and don’t leave you hanging without refilling your drinks! The food is absolutely delicious and hits the spot every time! The chili cheese fries are fire with that nacho sauce! If you get a French dip add bell peppers and onions to it! I will never stop coming here! Love you guys!
