FOOD SHOPPING in South Beach for CHEAP groceries is somewhat limited!
PUBLIX Super Market is by far the BIGGEST and therefore the CHEAPEST for most everything. It's open 7 days 7a-11p at 1100 6th Street. Publix website & sale flyer is here. South Beach blocks are much shorter than NYC blocks, so PUBLIX is easily walkable or bikeable from all of South Beach. Or simply take the "Bus 123 South Beach Local" for $0.25 (see diff blog sect on Public Buses for details).
HOT TIP: Publix car parking is very limited except in parking garage, so suggest you NOT take one unless you have someone to sit in it as a driver to move it around. (More coming on Food Shopping)
