    Corn beef hash
    Ed M.

    Caught lunch while shopping at the outlets. They had a corn beef hash plate (my breakfast go to meal). Cooked just right. They also offer beers and cocktails.

    My family and I had a great experience at this location! It's been so long since we've had ruby's diner and we loved that the ambiance hasn't changed. It's still giving that old school vibe that we love and cherish! The staff here was amazing, super friendly & prompt! We throughly enjoyed our meals. Plenty of seating inside and outside. We would love to dine here again!

    Fish and chips.

    Can't go wrong with Ruby's Diner. Been to this location a few times with the family. My wife and I decided to dine in this weekend, January 17th. We were greeted when we walked in right away. The host didn't make a big deal with us bringing in our stroller. The place is the same. Old school looking, clean with friendly staffs. We ordered their onion rings and fish & chips. Did not disappoint with the flavor and freshness. My wife loved their onions rings and one of best fish and chips I've ever had. Juicy on the inside, not dry as some other places would have served it. However, it's only served with 2 pieces of fish. Their onion rings could have been serve with better portions as well. They're not cheap with sauces, as we asked for more tartar sauce and delivered 2 to our table. Will definitely go back here again.

    Original malted waffle

    Ruby's Diner reminds me of college. We had a location nearby my alma mater so when my coworker suggested we go here before we headed back to the airport, it was super nostalgic for me! Despite this location being under construction during our visit, there seemed to be a good flow of patrons and we also were attended to quite well. I ordered a cup of coffee and let's just say I got my fair share of refills. For my food I ordered the original malted waffle with a side of sausage links and eggs over easy. The food came out hot and fresh and I definitely didn't leave hungry - just with a lingering desire for more waffles. Mmmm!! Also since it is October aka spooky season it was super cute that they had decorations up inside and outside the storefront (even while they were in the process of construction). It was definitely a nice touch! Thanks again, Ruby's Diner Carlsbad!

    这家餐厅完美复刻了上世纪50年代的复古风格,从怀旧装饰到招牌菜品都还原了经典美式 diner 的原汁原味。无论是餐食口味、分量还是服务细节,都完全符合甚至超出预期。服务员会贴心地为孩子们提供折纸小汽车作为消遣。尽管整体环境略带岁月痕迹,但毋庸置疑,它绝对是周边区域内最值得选择的美式diner。 Good old school 50's style diner with all the decor and all the dishes that you would expect. Everything meets or exceeds expectations, and the servers were very good with giving our kid paper cars to play with. The place seems to be showing its age a bit, but definitely the best diner option in the immediate area.

    This Ruby's feels like the end of an era. There used to be so many more Ruby's (on the pier), so I feel like still finding them is a real treat. This restaurant is a little smaller than other locations, but still has fun decor and a cool train that runs along a track at the ceiling of the restaurant. We had what one comes to expect from a Ruby's - friendly service and tasty diner food. I ordered the BLTA and while it wasn't the healthiest choice, it sure was good. I regretted not ordering a shake or cherry Vanilla Coke on this visit.

    I was reminiscing about Ruby's Diner, one of my favorite dining locations at the Oceanside Pier. They had closed many years ago and the building recently burnt down. But after doing a search online, I realize that they had a location in Carlsbad. This is my review of Ruby's Diner in the Carlsbad outlet mall. I am very happy that this Ruby's Diner is only 15 minutes away from downtown Oceanside. Although I don't come to this mall frequently, I may start returning more often thanks to my experience eating here. Ruby's Diner is known as a Classic American Diner that is well known for their burgers, fries & milkshakes. They're also famous for their vintage 50's & 60's themed decor & music. Their interior is very spacious and accommodate groups and families easy. You can also choose to sit outside on the patio as well. The vintage theme has various paraphernalia and decorations from the 60s era. They also have a functioning train set that runs a track on the ceiling above. The kids love it! I think the only CON I found for their atmosphere was in regards to their men's restroom being too small and only having 1 stall & 1 urinal. Their service is always courteous, fast & friendly and I love their uniforms. Although their menu is based on an American diner theme, there are many other options to help diversify one's dining choices. For breakfast, you can find items like eggs Benedict, omelettes, avocado toast, breakfast burritos, biscuits & gravy, chicken fried steak, waffles, pancakes, French toast, and of course, a typical American breakfast with eggs and bacon. Their lunch and dinner menu is just as extensive. Their portions are very fair considering the price, and overall, I love the customization options for customers who want to create their own flavor experiences by mixing & matching ingredients. My most recent experience was with a Cobb burger, Cajun Fries and a Salted Caramel Milkshake. I loved the variance from salty bacon, to juicy burger, to seasoned crispy fries & the sweet sips of heaven! Anytime I want a true vintage dining experience, I come to Ruby's Diner in Carlsbad to send me down memory lane. I recommend!

    This place is currently going through renovations, however it's open from dine in. The staff there are very friendly. Their burgers, fries, salad and shakes were delicious!! Yes... my kiddo enjoyed his burger so I didn't get a chance to take a photo !

    Do they still have beignets?

    They were included in the breakfast I ordered on the menu....but they didn't come on my plate. Perhaps they were out that day or they have stopped keeping them on the menu.

    Stumbled across Burger Lounge due to my little monster craving for some burgers for dinner. A quick…read moresearch online led me here... Let me start off by saying I initially thought Burger Lounge would be great but heading to the closest In N Out would be just as good and at a fraction of the cost. Luckily for me, my little one refused my attempted coaxing. Parking was a breeze given the fact that the lot is massive- perfect for the neighboring businesses and the busy foot traffic coming and going. Our party of three were immediately greeting with a smiling young gentleman standing behind the register. At first glace, the restaurant was massive is size, very spacious, modern, and 100% well kept/tidy. Seating and decor was simple enough but still had a classiness to it. We placed our order with the smiling gentleman [whom I learned was ANDREW]. Dinner consisted of: *KIDS MEAL: Cheeseburger with onions, lettuce, and EXTRA pickles *BACON BLEU BURGER *TRUFFLE-MUSHROOM SWISS BURGER *LARGE HALF & HALF [ tallow fried onion rings + fries] *DRINK Food: I kid you not, EVERYTHING WAS DELICIOUS!!! The order was made beautifully- presented well and cooked flawlessly. A+ for taste and presentation, which I totally didn't expect. Brioche buns were fluffy yet charred just enough on the grill to house all of the ingredients. The patties were flavorful and juicy. The goodness didn't stop there- BD mentioned Burger Lounge's onion rings being the BEST he's ever had!! Quality is absolutely undeniable. Above all, this burger joint runs smoothly thanks to the incredible staff. Each and every person we encountered was kind, polite, and so very eager to help with whatever requests. The only complaint I had was the terrible internet connection. Come here expecting to put your phones/tablets down even if you don't want to. LMAO. 5/5 stars but I'd easily give them so much more. Dinner was absolutely delicious and I am so sad that this particular Burger Lounge is soooo soooo far from home. I will 100% make it a habit to stop by whenever I happen to be in the area- THEY ARE TRULY THAT DAMN GOOD!!

    I loved coming here for burgers and fries. Especially being a vegetarian, this is the only place…read morethey have really impossible burgers. Unfortunately we just learned that they now dry everything in Beef tallow. Needless to say we won't be coming here any more.

The burgers were phenomenal! The blue cheese was sooo good! The truffle burger was incredible! I thought the Better Mac would have been my favorite, and it was still good, but surprisingly, it wasn't my fave over the three. The chicken sandwiches are HUGE but I wished the tenders were tossed in the sauce/seasoning. They add the garlic parm on top of the tenders as they're assembled on top of the bun, so it doesn't completely coat the tender. IMO, it would be more flavorful tossed. However, the aioli sauces are just so delicious and to kill for! Even though this is also a smash burger leave, their burgers aren't thin and had a lot of bite to them! They're so worth it and hands down much better than across the street!

    I think this is the first time I started my review, before even getting my food. That's how slow…read morethe service is, they were crazy packed (65% capacity maybe) but looks like they only had 3 people working 1) For all waiters/waitresses reading this. A PEPSI is NOT the same as a COKE, a Hot Dog is not that same as a Corn Dog.... AND Sweet n Low is NOT the same as Splenda. If I would have known they only have Splenda, I woulda ordered a Coke. But she said "yeah, we have sweet in low" Now we wait for our food and I'll continue the review. Mozzarella sticks were okay. Oil might be old cause they looked darker than normal but the batter was good and cheese sorta melted. 3.5 stars Ordered carne asada fries based of the waitress recommendation. It was okay. Fries were good, cheese was good and good amount, sour cream and guac was good. Carne asada was mid and amount was not that much. Being generous 4 stars Tea was good 4 stars. Philly was decent (wife got it, it's her review). 3,5 stars Below is reviews from my son who was STARVING and just finished a 10 day wrestling camp. Mac & cheese 2 stars. Cheese is viscous and strong Armenian cheese flavor Burger was 3 stars. Needs to be bigger and more juicy Mozzarella sticks 2 stars We not from here so won't come back for sure. Service wasn't great. She was nice but I think over whelmed with customers The Cheese Cake however, saved the day. 5 stars as in I would get it again and again. Once it died down, waitress did come by more often. Over all 3.5 stars but I don't feel right giving this place a 4 so I have to go with 3 And then we get the check and there is a 3% Green Fee (not on the menu but on the check) So that dropped the waitress tip from $30 to $15. But they earned that $5 Green Fee
