Buying groceries ranks in my least fave things to do, and thus, I haven't actually purchased food from Smart & Final. So, I can't report on the quality of the sustenance available here. It's bulk/discount buying without a membership card, so you don't have to make a commitment to hoarding more than you need.
I usually end up here when I am looking for something random. Once, I showed up looking for Swedish Fish, and despite their serious candy aisle with sweets served up in convenience store bulk, there were no fish! Boo. On my last visit, however, they came through! They have an entire aisle of to go cups with lids and a slew of packaging options from baggies to paper bags and a large selection of food boxes. I even saw cardboard drink carriers! It's like a mini-restaurant supply shop, which can be handy when you are planning events.
