I didn't purchase this cart to use as a bar cart, but as a plant stand for my orchids. It is sturdy enough for the 7 seven pots, so I'm assuming that it would be sturdy enough for a few bottles. As others have said, yes, the caster covers are plastic, but I have no issues with that since the cart wasn't expensive. My husband put it together by himself in 15 minutes. The glass top and mirror bottom had to be sort of jiggled into the space. They looked perfectly oval, but i think the cart isn't. However, it isn't anything that is visible, unless you go poking around. I have hardwood floors, so it rolls fine. I don't think that it would roll too well on carpet. You might have the bottles wiggling around. All in all, for whatever purpose, I'd say that it is good looking and good value for the price.
