I am not a fan of Swizzle.
Every time I have gone, the bar has been absolutely packed. Which is great for the bar and could be fun for people watching but its so loud and theres so few places to sit (unless you get lucky and manage to scalp a seat).
There is a pool table but good luck playing a game without hitting someone.
Drinks are average price if you can manage to get the bartender to serve you. Ive waited upwards of half an hour while standing at the bar, cash in hand, without even getting glanced at. Ive been skipped over so many times that random other groups of people have bought my drinks for me!
And the second thing I dislike most about Swizzle is the lack of smoking patio. As a smoker I always judge bars harshly when they don't have an enclosed patio for me to bring my drink and enjoy a cigarette.
So in all I would suggest Swizzle to people who love big groups and not hearing what their friends are saying, dont feel like drinking, and enjoy being crammed into a stuffy sardine can.
