JD Wetherspoon's pre-tax profit rose in the full year as its "cheap and cheerful" pubs pulled in customers seeking pink gin and coffee as well as traditional beer.
This is despite the fact that Brexit worries continue to hurt overall consumer confidence and spending.
Wetherspoon, like most restaurant chains in the UK, has been battling increased costs due to a minimum wage hike, higher property prices and power bills.
It has also been investing in its more labour-intensive food and coffee business.
It has however still managed to attract patrons to its more than 900 pubs in Britain and Ireland as it keeps drinks prices low, providing a cheaper alternatives for people who often face high costs to drink in pubs, restaurants and clubs.
Its pre-tax profit after exceptional items rose to £95.4m for the year ended July 28 from £89m a year earlier, although before exceptional items, it fell 4.5% to £102.5m.
"Costs were quite high as we invest in the business and gardens and kitchens and people," Chairman Tim Martin, a vocal Brexiteer, told Reuters.
Initially called Martin's Free House, Wetherspoon has also been spending to upgrade facilities at its older pubs.
Total sales rose 7.4% to £1.82 billion, while like-for-like sales rose by 6.8%, with a jump in bar and food sales.
Analysts said the company had fared a lot better than many of its rivals. But they warned however that the rate of sales growth had slowed, putting more pressure on the company's already-thin margins.
Rival Greene King said earlier this year that a wet summer and poor sentiment had hurt its sales in its new financial year.
Wetherspoon's like-for-like sales rose 5.9% for the six weeks to September8. Tim Martin said growth recently and in the full year had come from the sale of coffee, real ale and also gin.
"Everyone is drinking gin. Even the guys from the building sites down the road are drinking pink gin with strawberries. It is quite a revolution," he said.
The company's performance comes at a time when the UK's pub sector is brimming with deals.
Greene King is set to be bought by Hong-Kong's Ck Asset for £4.6 billion, while Slug and Lettuce pub chain owner Stonegate has agreed to buy Ei Group for £1.27 billion.
