There is always a line here and for good reason. Other than Eggsmart, Lady Marmalade knows the permutations of eggs and its eggs bennies. You can even get them gluten free!
Aside from eggs, they punch up their comprehensive AM menu with some sweet and savoury items like poutine (served on weekdays only), Huevos Rancheritos or a baked French toast.
It's worth the wait but I would try to get to this bright room as early as possible.
