UK restaurant chain Las Iguanas is turning up the fiesta spirit this spring with the launch of Marg Month – a full month dedicated to one of the world’s most iconic cocktails, the Margarita.
Throughout March 2026, guests across the UK are invited to gather their margarita-loving friends and celebrate with a vibrant line-up of cocktails, special menu offers, and even a free margarita giveaway for those celebrating birthdays during the month.
Known for bringing the flavours and energy of Latin America to British dining, the restaurant group is embracing the season with bold cocktails, lively interiors and a party-ready atmosphere designed to capture the spirit of Mexico and South America.
A Month Dedicated to the Margarita
During Marg Month, Las Iguanas will be shaking up a colourful range of margaritas. Alongside the classic lime version, guests can enjoy fruity favourites including strawberry and passionfruit, as well as several limited-edition creations created especially for the celebration.
Among the new additions are:
-
The Bahian – made with Altos Plata Tequila, triple sec, lime and warming spices, topped with toasted coconut and spring onion
-
Hot Honey Mango – a sweet-and-spicy mix of Altos Plata Tequila, triple sec, lime, mango, hot honey and chilli
-
Margarit-eh – a non-alcoholic alternative made with Almagest Blanco, lime and organic bitters
Each drink highlights the zesty citrus flavours and refreshing character that have helped make the margarita a global cocktail favourite.
Free Margarita for March Birthdays
As part of the celebrations, anyone born in March can claim a free margarita on Tuesday 24 March 2026.
Guests simply need to sign up via the official Las Iguanas website to receive a promotional code, then present it with valid ID when dining in restaurant. The offer covers a £10.95 margarita, redeemable against the cheapest margarita on the bill.
The birthday giveaway adds an extra reason for guests to gather friends and celebrate during the month-long event.
Tapas, Brunch and Margarita Pairings
The festivities don’t stop at cocktails. Throughout March, the brand will also highlight several of its popular dining experiences, including:
-
Tapas bundles
-
Bottomless Tapas Tuesdays
-
The restaurant’s all-day Bottomless Brunch
Each offering is designed to pair perfectly with a refreshing margarita, making Marg Month a full dining and cocktail experience.
Bringing Latin American Flavours to the UK
Founded in 1991 in Bristol, Las Iguanas has grown into a popular destination for diners seeking the colour, energy and flavours of Latin American cuisine.
The brand is known for its lively soundtrack, colourful décor and menus inspired by the culinary traditions of Mexico and South America. Alongside meat dishes and tapas, the menu also features a wide range of vegetarian, vegan and flexitarian options, ensuring there is something for everyone.
From freshly made dishes to vibrant cocktails and friendly service, the restaurant aims to recreate the celebratory atmosphere often associated with Latin American dining culture.
Marketing Director Tom Patrick said the margarita celebration was a natural fit for the brand.
“At Las Iguanas, we love any excuse to celebrate the hugely popular Margarita, so Marg Month is the perfect opportunity to do this. It’s bold, bright and brings the fiesta wherever it goes, just like our restaurants. Whether you’re a classic lime fan or prefer a fruity twist, there’s a Margarita for everyone. And treating March birthdays to a free one felt like the perfect way to say Salud!”
