Wish I'd found this place earlier. Prices seem a little better than a bigger, Austin-based, chain competitor, and they've got a much better selection of local produce and other local items. The free garage parking is a huge plus, too, especially in the Strip.
My new Strip strategy: hit the few really good places in the Strip for specialty items (cheese/pasta/Italian in one place, latino and Asian in others), then get everything else from RBN.
