I second both of your picks. J Ryan's has an excellent selection of craft brews on tap and also a cooler of 22's you can buy to take home. Brilbeck's is the best beer store in town hands down. Dewitt Wegman's is probably number 2. Cheers!
I live in auburn and don't get out to syracuse much but if you find yourself in auburn try Swaby's and Parker's for draft and best selection for a store is between wegman's new beer isle and d&l truckstop.
If you like Polish beer the European Market on Erie boulevard (near liquor square) has polish and possibly some Ukranian brews. There is this one porter I love (zywiec porter). Pretty tasty and haven't found it at other places.
