I've had many a fishbowl at Wando's but I have no idea what this Wanda's is. I'm sorry but the bar scene is so much a part of college life in Madison, I'm glad I finished school just before this stuff started to go through. A Fishbowl is a group activity, usually participated in with 3 to 6 people. It's not, "let's drink a fishbowl", it's, "let's do a fishbowl".
A fishbowl is literally a medium sized fishbowl filled with an alcoholic punch and ice.
