A bit on the pricy side but they offer different sized burgers as well as the gluten free option of wrapping in lettuce. And important allergy thing to note is that the fries are cooked in peanut oil (as it's healthier) but also that the entire place has boxes of peanuts by the tables.
If you want recommendations, I've recently come to like the cherry milkshakes. It has an intriguing slightly bitter, slightly sweet aftertaste.
