Recently, I posted about a bad experience at Taillevent in Paris. Much of the tone for the evening was set by them squeezing 5 of us into a banquette obviously designed for 2.
Normally, if I am given a table I don't like, I'll ask to be reseated. If they don't accomodate, many times I'll leave.
My pet peave is this: In high end restaurants (more than $25 entree), I think that there should be no "bad tables". ie: two tops when other duos are at tables set for four. I realize this might be a tall order, but during my recent trip to Europe, all the other michelin starred restaurants (Zuberoa, Panier Fleuri, St. James (bordeaux) and L'Astrance) all had superb seating - I would have been happy at any table.
I feel like if I'm paying for an Ocean Front room, I shouldn't be seated with a view of the parking lot. (hotel analogy)
