Jason Nightingale had a knack for sniffing out a try during his Rugby League career and now it appears the retired St George Illawarra winger has mastered another skill – as a barista who can brew up a decent cup of coffee.

Brydens Lawyers NSW Blues backrower Tyson Frizell took his infant son Axton to visit his former Dragons teammate and the player affectionately known as 'Gypsy' at the official opening of his new business, Flow Espresso, at the Dragons' spiritual home in Kogarah.

"@flowespresso officially opens today," Frizell posted on Instagram.

"Congratulations to @gypsy_no5 and @mark_somboli

"Best coffee in Kogarah."

Nightingale, 32, played 266 games for the Dragons and scored 110 tries before making the decision to retire at the end of last season, while fellow winger Nene Macdonald also moved on to North Queensland.

Zac Lomax and Jordan Pereira are tipped to fill the wing spots at the Dragons.
