Restaurant review: Skylon

After some research for a business dinner close to Waterloo, I booked Skylon in the Royal Festival Hall.
The room was vast, gymnasium sized in fact, with a level of noise approaching that of a teenage basketball match, but the floor-to-ceiling windows opening up on the Thames make it spectacular. Shame they did not give us a window table as requested. The waiters are all in star-trek-like uniform, in tune with the retro-futurist location and name, plentiful and nice enough but they probably were beamed to another planet during main course as service got slower and slower.
The wine list is predictable but good, the sommelier was new and knowledgeable.
I haven't mentioned the food, and that's because it was passable. On the positive side, my onglet was perfectly uncooked as I ordered and like it but the smoked mackerel salad was some potted fish, swimming in light mayonnaise dressing and cos lettuce.

Final verdict: Skylon joins OXO in the category "you pay for the view, not the food".
