I was there last night, and I have some good news...
Lamb chops are back on the barfood menu, but not the Irish stew. In place of the burger-with-the-lot are "burger bites" - 3 palm sized burgers with the beef, cheese and lettuce once (and chips). They have have steak-and-blue cheese on ciabatta and beef short ribs with HP sauce.
There were videos of Guinness ads, quizzes, dark chocolates to go, the brewmaster of course...but the stout was poured onto shot glasses from cans and bottles. (So I ordered mine from the bar - unadulterated!) Oh and a demonstration of "Guinness Surge" - a method of serving supposed to give it more body but it didn't taste any more palatable to me.
Giving this stuff to me's a waste.
