Most bars fill up glasses with ice before adding anything else. Also, always used cracked ice, never cubes. Not only do pouring caps look more professional, and make it appear as though you are pouring a generous serving, they are also a lot faster to use than hassling with bottle caps. Most mixed drinks that don't have a carbonated liquid as part of the ingredients are shaken. Many open shakers are designed fit perfectly over the pint-sized beer glasses normally used for serving most draught beers.
Strainers are paddle-shaped with slots for the liquid to drain through.
Most of them will have a horseshoe shaped spring around the outside. Like shaker sets, your strainer should be made of stainless steel, never plastic. Some are two-sided. Much like the mousetrap, people are continually trying to reinvent this device, with little or no success. Many of these also have bottle openers as well as small knives to cut the foil on wine bottles.
