I recently visited Ruby’s inside South Coast Plaza Orange County and ordered the fish and chips. Overall, I had a positive experience. The food was delicious, the service was friendly, and the atmosphere was fun and nostalgic. However, the fish quality was not that perfect. The batter was a bit dry and overcooked.

Simple classic American diner. Good food typical of what you would expect. Classic American cheeseburger was good but nothing special, fries are free-flow! Caesar salad was tasty but grilled chicken was a tough and dry. Overall enjoyed my time there and would pop in for a quick stop.

One of our favorite restaurants. Their burgers are delicious, so many shakes to choose from, FREE REFILLS ON FRIES and so many different food options (you can get breakfast all day). All the adults and all the kids in our family love it.

Stopped in Saturday morning before the mall that Ruby’s is attached to was open, so it was nice and quiet. The service was good. The food delicious and the atmosphere a bit upscale given the upscale mall it’s in.

I absolutely love this Ruby’s location. All the staff is friendly and courteous and always have a smile for you. Lupe is the best server and I’ll keep coming back because of the outstanding service he provides. The food is delicious and promptly served, hardly any waiting. Highly recommend this Location!

Well, what a surprise to find Rudy’s here. It’s just not what we expected. We were seated right away and greeted fast. The drinks came fast. We ordered and the food came fast. That was all totally great. The food was hot, and fries especially were hot and crisp. Quality food is always appreciated. Thanks, Ruby’s.

Typical mall food, a bit on the expensive side for my East Coast mind. My wife’s burger was good, my son and I had chicken tenders and found them to be soggy, somewhat under cooked. The fries were good. Didn’t try the Cole slaw just not a fan. Not a fan of the Raspberry Tea and I gotta tell ya nowhere in the Costa Mesa area not a single restaurant has Sweat Tea. Apparently it’s just not a thing here.
