Did you wait on the street corner b/c there no place to wait inside (I’ve never been).
I do think that, at that price level, it’s totally appropriate to e-mail the restaurant to say something like, “I greatly enjoyed the food I had last night but found the 35-minute delay in being seated to be rather odd, especially since there the staff didn’t acknowledge what had happened. And waiting that amount of time wasn’t particularly comfortable because there’s no place to wait inside.”
Honestly, at even a quarter of that price, I’d be pretty miffed if I had to wait over 30 min for a seat when I had made a reservation…
I do think that any restaurant, at any price point, can have an “off” day, but I would imagine that an expensive restaurant would know how to handle it better (and it sounds like your situation wasn’t really handled at all).
