Pros
Laid back environment. Gives a person with no experience to learn and develop their basic bartending skills
No micro-management.
You can learn about Asian alcoholic drinks such as Saki, Japanese whiskey and Thai beer because that is what they serve on their menu.
When I worked there, there was no manager on staff the vast majority of the time, so you are in a sense in charge of the bar yourself and the hosts will take care of the cash register at closing.
Cons
It is lacking in the basic hygiene standards and protocols behind the bar.
There is no management, you are watched by cameras and the owner will call you if he sees you doing something he doesn't like.
You will receive very little training.
The owner did not seem to care about me at all or care to get to know me or any staff member in any capacity. Strictly business.
The storage for bar items and alcohol is all located in a waist-high crawl space that you literally have to be on all fours to grab whatever you need to re-stock. I've injured myself down there from lack of cleanliness.
No benefits.
