Would that be the Fox opposite the Hippodrome? Harviestoun Schiehallion used to be on the regularly, it was billed as cask conditioned Lager, the Fox used to sell that alongside Highgate Dark Mild, and Brew XI.
Birmingham has some excellent hostelries to sample the goods of small breweries; The Wellington, Bennetts Hill; The Post Office Vaults, New Street; Pure Bar and Kitchen, Wellington Street; The Old Joint Stock, Colmore Row (Not a vast selection of beer, but the interior is spectacular); not forgetting The Anchor, Bradford Street.
I'm loving the smaller breweries coming out of Cornwall. St. Ives Boiler Ale is magnificent, but Padstow Gold is Cornish Summer in a pint glass. Not long till I'm down there sampling a few more.
