We had reservations at The Eiffel Tower Restaurant for my birthday. I had relayed the dress code to everyone, but my brother showed up in shorts because he forgot to pack his slacks. This turned out not to be a problem. The host at the base of the elevator asked his size, and by the time the elevator arrived at the restaurant level there was a pair of nice black slacks for him to wear. I know lots of nice restaurants with dress codes keep an inventory of coats and ties, but never thought about slacks.
