Amazing burger and really big pattys, the shake was 10 bucks but dam that's an amazing shake, the loaded Mac and chicken was insane I am not kidding it weighed 3 pounds prolly so delicious, super high quality zero grizz chicken and the Mac and cheese was insane pictures do not do it justice it was way too much food. Just the Mac Loaded Chicken was enough to feed 4 children I bet. Yes it's higher priced but the quality and portion size matches that price.

OKC Fried Onion Mash wasnt bad, but a little basic. feels like they expect all the flavor to be in the sauce, which ends up underwhelming, cause the burger itself should be where the flavor is.
Chocolate Shake was great, probably one of the best I've had in a while, but pretty expensive for the amount you get
Fries were incredibly disappointing, like i did not know it was possible to make such awful fries. fully and completely soggy, like they had been sitting in their delivery box all day under a heat lamp. absolutely no salt or any form of seasoning on them.
i feel like this place has potential, but the overall product isn't quite good enough to justify the prices. might try again in the future.

I am so excited that mashed burger came to Stamford, I have had it twice it has been excellent both times and is far better than the other burger options we have around here (10x better quality than shake shack) as an ex-Californian I was looking for an in-n-out replacement of the same caliber and I found it in mashed burger.

Too much sauce all over, making the fries soggy. I would order it again but we consistency would be awesome!
