I love 'the Swiz'. I ended up here on a Saturday night after a concert and we had a great time. It is a rare feat to find a dive bar with generally pretty good looking people in it! Also, I only verbally ordered a round of drinks once and the bartender remembered it for the rest of the night...just had to walk up to the the bar and presto, the drinks magically appeared on the counter!
I noticed the other reviews of old people frequenting the bar... Kind of strange because I don't think there was anyone over 40 at the bar when I was there. This may also depend on the time of day, we did not show up until around midnight on a Saturday.
