About One Under
One Under is an indoor entertainment venue in Glasgow, Scotland, where mini golf sits alongside cocktails and other social games. It runs two themed 9-hole mini golf courses, and guests can also play interactive darts, shuffleboard, arcade games and pool. A cocktail bar gives the place its lively feel, and the space suits meet-ups with friends, family or colleagues. It can be hired privately and hosts live DJ entertainment for events.
Games are booked through the venue's website, where customers pick a date and time slot, give their contact details and pay to secure it. Cancellations and rescheduling are possible up to 48 hours before the game time, though requests made inside that window may not be accepted, so it is worth contacting the venue directly. Payment can be made with Visa, Mastercard, PayPal, Apple Pay or Klarna, and gift vouchers and e-gift cards can be bought online, by phone or in person, then put toward golf admission or drinks.
Several groups pay less at One Under. Students with a valid student ID get £7 tickets for 18 holes Monday–Thursday at Brighton, with group packages and occasional drink offers. Concession tickets for over 65s come in around £9.00 to £9.25, child tickets around £8.00–£8.50, and a family package for 2 adults and 2 children is £32.00–£34.00, with anyone under 16 needing an adult with them. NHS, emergency services, teaching, social care and armed forces staff can use a Blue Light Card, and carers and military personnel are covered too; they book a student-priced ticket and show the card or equivalent ID on arrival. Staff get an employee discount, usually including reduced or free food and an employee assistance programme, and new customers can get a first order discount by signing up. One Under can be followed on Instagram.
