I've been about 3 times now for lunch, and have found the burgers to be delicious on their own. I do appreciate the topping options, and the BBQ and Teriyaki burgers are especially good if you like flavorful and messy. I especially appreciate their bun options, including a gluten free option for our daughter. It's also great that they offer different 'done-ness', and medium rare comes out perfect, slightly juicy and very tender. Whatever meat or grind they're using just makes for a perfect burger.
The fries, while standard, are also incredibly good. The garlic fries are also worth giving a try.
I've been here a few times, and plan to make it a pretty regular lunch spot.
