Llocated in the Brewery Shopping Centre, it is set to welcome its first guests tomorrow (December 11).
It will feature games and activities, including electro-shuffle and Sixes Cricket batting cages.
The venue is taking over the former Bunkers site, following a six-figure investment.

There will be two Sixes Cricket batting cages where guests can face a virtual pro bowler, with real balls thrown at varying speeds of up to 75mph.
Options include simulations of the World Cup and T20, with various difficulty levels to cater for all.
Other games on offer include electro-darts, pool tables, crazy golf, and ping pong.
Sports fans can also enjoy live action on 146-inch and 65-inch TVs.
New VIP areas can also be booked for private parties and events.
To keep players fuelled, a menu will include pizzas, nachos, dirty fries, and sides such as chicken tikka kebabs, corn ribs, and warm halloumi bites.
Vegetarian, vegan and gluten-free diets are all catered for.
There are also 12 signature cocktails, as well as a variety of alcohol free, beer and cider on draught, including Guinness and Inch’s, wine and soft drinks.
