It's good but nothing amazing. I like that it's grass fed beef.
Some burgers make you sad that it's over and you feel bad afterwards for stuffing yourself, but here it's just I'm going to eat this since it's not awful and it's a burger. It didn't leave me wanting more. I haven't had anything other than the burgers.
Ambiance/service: They consistently have good service and it's a good place to get drinks. It will be very busy on the weekends and you'll have to wait. During weekday dinners, it's usually only busy if it's warm out.
Where to go instead:
My favorite all time burger and fries are from UW's Memorial Union and Union South. But I haven't had it in a couple years since I'm a vegetarian now. It still looks good though and everyone who eats it per my suggestion says it's great.
