This is a serve yourself bar serving keg beers and wine from a series of taps.
The process is you get a card like a credit card upon being seated that then allows you to operate the self-service machines and you settle up when you have finished. The keg beers are served in half or full pint measures ( stronger thirds & two thirds measures were being served from an upstairs bar noted on a visit on 29/10/24 ).
The bar itself looks out on Circle Square and has an outdoor seated area at the front.
