I have always really enjoyed this bar. The waitresses all wear funky ABBA-inspired outfits and there are great drink and food specials.
I come from time to time with friends and enjoy the aquarium quite a bit (especially my favorite little fish who I've affectionately named Bob). The service is pretty good most days, but can get iffy from time to time. I especially frequent the place during the Thursday night pub crawls Silverton hosts, with $1 drinks.
I highly recommend this cool little respite.
