The Heineken Pub, situated in Hall 8 at Parc des Expositions alongside the stadium, will open its doors at 11.00am and serve beer, soft drinks and a range of food, right up until 2.45pm - 15 minutes before kick-off.
"Following on from the success of the Heineken Pub in Beziers last season, when Munster met Castres Olympique in the semi-final, ERC and its title sponsor have once again arranged for a special facility for fans of both sides to mix before and after the game," said ERC chief executive Derek McGrath.
"It is one of rugby's unique points that the supporters of both teams mix so easily and freely before and after games and the Heineken Pub will enable the Toulouse and Munster supporters to reacquaint themselves following their epic semi-final clash in Bordeaux three years ago."
The Heineken Pub will also feature music and other entertainment, and there will also be six bars open around the ground. The Heineken Pub is set to close at 8.00pm.
