Bishop's cellar is on the water front, 7-8 blocks away from the Casino.. You can take the boardwalk all the way to it.
They are a wine and premium beer specialty store, the selection isn't huge but it always changes, They always have some lambics/sours on hand and stuff you can't find anywhere else around here.... def worth the walk. They fill growlers too.
