Only 3 tables being used in one section when I went past this afternoon. Disappointing to see TLG and Bluetit down there singing 'you're not busy any more', no need for that.
I gather it's not part of the half price meal deal that's running Monday-Wednesday through August (I assume their meals are classed as deliveries) which is really going to affect its trade on those days. Saying that, there wasn't a queue on either section on Saturday afternoon which surprised me as it had been busier than an Etien Velikonja book signing the weekend before. I haven't seen much customer feedback about it yet, I'd be interested to see an article if it exists.
