A friend of mine did that a few years ago, Manuel dropped a small rodent of some kind under her table and then repeatedly rubbed her leg "looking for it".
I went on Tuesday night with and I can confirm that Manuel does indeed "lose" a rodent under the table and indeed does stroke a woman's leg looking for it. That woman on Tuesday was Mrs Alfie22! In terms of review I guess I should put it in the "Restaurant 2012" thread but seeing as you asked;
Starter - Tomato soup - not bad, probably out of a tin with a bit of seasoning added (Manuel adds Basil in a unique way)
Main - Chicken supreme - couple of people on our table felt this was too spicy but I quite liked it, vegetables were a little on the under-cooked side mind
Dessert - Chocolate torte - A bit of a slither size portion but nice enough
It's £45 a head and there was nothing on that menu (it was set) that I couldn't have done myself and if I'd had it in a non-performance eating out setting I wouldn't have paid more than £20 for it. That leaves £25 for the "show" which is probably about right - it's pretty funny, Manuel is excellent, Basil good, Sybil a little bit like that woman who banged the glockenspiel in Grease! I'll probably get tickets for my parents in December so I guess that means I'd recommend it for overall night out. Just don't expect fine dining.
