Great burger but way under staffed. Order of 6 and all the food was cold. Fries cold. Resturant cold. For $136 I would at least like hot food. You can do better

Best fast burgers in south OC, slightly crispy patties, very thin so always order a double! Love the fresh jalapeños! Also love that they only use grass fed beef!

Best burger ever
So tasty and fresh. Grassed boss burger is amazingly delicious. Their boss sauce is great. And we received the best service. The workers are all so nice. We had a fantastic experience. We’ll tell our friends about this place.

Unique concept, but disappointing service.
I came a couple minutes after opening and the doors were still locked. I was in a big rush so this made me kind of annoyed. After waiting in my car and trying again later, the doors were finally opened.
Even though I was the second customer to come in, they were already running way behind because they just received a bunch of mobile orders that they wanted to do first. I didn’t mind considering that they seemed short-staffed and I appreciated the heads-up. I do feel, however, that they should prioritize dining customers rather than mobile orders because there ended up being orders just sitting on the counter since no one came to pick them up while actual diners were waiting endlessly for their food.
I waited for about 20 minutes for my meal and it was pretty underwhelming. The fries were cold and the burger was pretty bland. They have a pretty interesting way of serving their burgers — one half with the cooked ingredients, the other with the veggies, then the customer puts it together to form a burger. Because of this, I don’t understand why it took so long considering they don’t even put the burger together for us.
TLDR:
* Prioritized mobile orders over dining customers
* Didn’t open on time
* Food was underwhelming
Pretty disappointing, but I’m willing to stop by in the future and give them another chance.

Great tasty burgers that you can customize to your liking. Well worth the time to chomp into the juicy patties with the condiments you want in it. Of course they have their own selection of premade burgers but that takes the fun out of having your own burger choices.

What is beautiful tech friendly modern and welcoming setting. I had to try this place out and I was not disappointed ordering was really easy you have several options, you can order from the app, you can order from a touchscreen kiosk, and finally you can order at the register.
Since this was my first visit I ordered from the register everybody was incredibly polite and friendly and even made the experience a little fun let me hear is exclusively grass fed and there is no hormones or antibiotics or anything in there.
I ordered a spicy chicken sandwich, and then I added the boss bundle for $4.50 which gave me a side of fries and a drink. I love the chipotle mayo so I ordered two sides for my dipping sauce the whole process took less than 10 minutes. Sitting in the lobby there are two giant TVs for me to enjoy the furniture was markedly clean and I will be coming here again

I’m not sure why this place does not reach more. When I have visited, the business has been light. But in terms of burgers, simplicity, and quality this place should be more comparable to an In-n-Out in terms of a following based on quality of food and even better customization of options. It’s a balance between knowing what you want and navigating a build your own menu. Maybe there is some resistance toward putting your mind through a process when you just want to eat what you already know or try a preprepared option. Maybe one suggestion is to offer some creative pre-prepared options for someone who doesn’t want the build your own experience. Like Cold Stone ice cream, you can completely build your own but also choose from many combinations of ingredients that may be better than what you are in the mood to “build” on a given visit. Sometimes you just want something good and not have to create it yourself. But overall, always a great meal experience once you get through the process.

I came in for my first time and Max was absolutely wonderful! I wasn’t sure what I wanted he was extremely polite, kind and helpful! Thank you for hiring employees like Max who make just getting a burger a really excellent experience. It’s employees like him which makes a huge difference in where I and others choose to go for food! I will absolutely be back and will make this my number one burger place from now on! Now can’t wait to get home and try it!

The burgers were absolutely delicious. The wheat bun was incredible soft. My requested over-medium egg was a little more on the over-hard side, but I’m forgiving. The taste was extremely fresh and well-seasoned.
The sweet potato fries could have used a bit of seasoning, like salt or something like that, but otherwise were good.
My only issue was that the price was a little high for my taste. I’d still be willing to go back.

I have finally found the burger I’ve been looking for since moving to California.
The meet is excellent, not dry, and not soggy.
All the ingredients were fresh. Fries were awesome. Unfortunately, like most restaurants, they lable yam fries as sweet potato fries, but they are good anyways.
The only real critique I have is that their cup lids don’t fit properly.
But I will never go to another burger place while they are here.
