My local is an Ember Inns pub and according to their app it is:
Carling £4.10
Coors £4.55
Stella £4.75
Estrella £5.10
Peroni £5.50
There is more than that, I just highlighted a few, I’d go for an Estrella or Peroni.
I’m going to Bottomless Brunch in a few weeks hopefully, a full English breakfast and unlimited Peroni for 2 hours for £25.
