I come here occasionally during off hours and it's still busy! Not as busy as evenings & weekends though.
Love the model units especially the tiny units that are relevant to the urban dweller. Nice ideas on layout, furniture and accessories.
Store layout if fine, self-serve is convenient. Staff are helpful, if you can get ahold of one (sometimes it feels understaffed - either I can't find anyone or there's only 1 person and 3 customers waiting to ask questions).
I like their fast, convenient and low-priced meals when i'm on the go.
