We won't be wearing jeans and sneakers, but how strict is the expectation to be wearing suits or jackets? Can we get away with slacks/trousers, button-downs, sweaters, etc?
Also, when we made our reservation we specifically requested the main dining room and not the casual area. Does this make a difference as well, not only with the dress code but with regards to the menus offered and service? Their website doesn't make much of a distinction between the two areas though I have heard that there is a difference.
