Contrary to its name, this cocktail does not have much in common with a classic Martini. Porn Star is a version that combines vanilla-flavored vodka, passion fruit liqueur, lime juice, and passion fruit purée, while a shot of Champagne (sometimes Prosecco) is served on the side.

To prepare it, all the ingredients, except sparkling wine, are poured in a shaker filled with ice and are shaken, and then strained into a chilled glass. The cocktail was created in the early 2000s by Douglas Ankrah at The Townhouse bar. Ankrah initially named it Maverick but decided to change it as the drink reminded him of something a porn star would drink. 

Espresso Martini is a rich and creamy cocktail made with a combination of vodka, espresso, sugar syrup, and coffee liqueur. All ingredients are first mixed in a shaker with ice, and then strained into a Martini glass. There should be a nice froth on top, which is usually garnished with a few coffee beans.

This cocktail was invented by Dick Bradsell, a bartending guru, who first named it Vodka Espresso, and then Pharmaceutical Stimulant. He first prepared it at Fred’s Club in the late 1980s for a young model who is now world-famous. 

Gimlet is a simple yet classic cocktail that originated in England. The cocktail is named after Sir Thomas Gimlette, who supposedly invented it at the end of the 19th century. In the past, Gimlet was made with equal parts gin and lime cordial (typically Rose's lime juice), but modern versions are usually less sweet and made with one part lime cordial and two parts gin.

The ingredients should be well stirred with ice in a mixing glass and served with a lime wheel garnish.

Bramble is a spring cocktail that was created by Dick Bradsell in 1984 in London. The cocktail consists of dry gin, lemon juice, sweet blackberry liqueur, sugary syrup, and crushed ice. It is named after blackberry bushes which are commonly referred to as brambles.

This refreshing cocktail has a strong aroma of fresh berries such as blackberries or raspberries. It is prepared by stirring ingredients with crushed ice in an old-fashioned glass, then pouring blackberry liqueur over the combination in order to create a marbling effect. 

Tom Collins is a classic cocktail hailing from London. It's made with a combination of gin, lemon juice, sugar syrup, and soda water poured into an ice-filled glass. It is believed that this refreshing drink was created by the head waiter at a London restaurant, and the drink was named after him.

Although it was originally made with jenever, these days the cocktail should ideally be made with Old Tom Gin, which is a bit sweeter than London Dry Gin used for John Collins. The first recipe for Tom Collins was printed in Jerry Thomas' book The Bartender's Guide in 1876. 

Pink Gin is an English cocktail made with a combination of Angostura bitters and Plymouth gin, hence its other name, Pink Plymouth. To prepare it, a cocktail glass is first chilled, then coated with bitters. Chilled gin is then added to the glass, which is traditionally garnished with a lemon rind.

A few ice cubes can also be added to the cocktail, if desired. It is believed that Pink Gin was invented by members of the Royal Navy, who wanted to make Angostura bitters more enjoyable by combining them with the sweet Plymouth gin (as opposed to dry London gin). 

Buck’s Fizz is an English cocktail made with a combination of champagne and orange juice, where the ratio should be 2:1, unlike the Mimosa, which is typically made with equal parts champagne and orange juice. The cocktail is served neat and undiluted in a champagne flute, and it can be garnished with an orange twist.

It was invented in the 1920s by Malachy McGarry at Buck’s Club in London, hence the name. Nowadays, Buck’s Fizz is especially popular at weddings, and it is sometimes used as a hangover cure.

Black and Tan is a beer cocktail that contains two types of beer: pale and dark. As the name suggests, beer is layered into a pint glass to display a combination of light and dark beer. To prepare it, one should slowly pour stout beer over the back of a bar spoon into a glass that already contains light lager beer.

The British tradition of blending beers has been present since the 17th century, and Black and Tan probably originated in England around 1889 when it was first mentioned in the context of a beverage. However, due to its political connotations, its name is considered disrespectful in Ireland, so it is often referred to as A Half and a Half.

John Collins is an English cocktail made with a combination of dry gin, sugar, lemon juice, and carbonated water. To prepare it, all ingredients are poured into a highball glass filled with ice, then stirred and garnished with a lemon slice and a maraschino cherry.

However, there are also many references where John Collins is made with bourbon instead of gin. It is believed that the cocktail was invented in the 19th century by a headwaiter at Limmer’s Old House, a popular London hotel at the time.
