This is the only ALDI I've been to so far (almost accidentally wrote ALDO; I've been to far more of those).
They have a great selection of boxed goods, with holiday-specific food items.
Very large frozen food selection.
Their produce actually looks and tastes really good!
I'm not sure about the other ALDIs, but this one is quite small. However, it doesn't really feel cramped and I've been able to find everything. They sort of have a creative way of fitting everything in, utilizing the space they have wisely.
Both times I've been here I've only come in for a few items, so I haven't had to deal with any (potential) stress of the no-bag issue. I have my own bags, though.
Cashiers are friendly and quick, and have patience for the customers, who are usually neither.
And of course. Like any self-respecting grocery store, they stock a few "grab 'em and go" items by the checkout. 4-packs of gum, baby. I fall for it every time!
