(Visited 08/2003): Located right off the NJ Turnpike (not far from the Newark airport), the Shoprite Liquor store is attached to the grocery store but with a separate entrance. Being a grocery store, parking should not be a real problem.
The first thing I noticed when entering were several signs that proclaimed you could not purchase alcohol at Shoprite with an out-of-state driverís license. With that in mind, unless you are CLEARLY over 21, you may be in for some problems buying anything here. I think that is a stupid policy so the "Service" score is being dinged accordingly. Unfortunately I saw the same sign at all of the Shoprite Liquor stores I visited.
The good news is you can actually find some good beers here. Some notables were Brooklyn, Saranac, Magic Hat, Victory etc. Unfortunately none of the local/regional stuff was available in singles. Aside from the usual macro bombers/Asahi etc., Sam Smithís were about the only worthwhile singles.
The staff is about the level of knowledge you would expect working for a grocery store chain.
Overall, I am sure there are beer stores with better selection but this is definitely worth a stop if you are in the immediate area.
