I am going to Vegas this July and am trying to figure out what to pack - with more airlines charging for additional bags, space might be a premium. What is the usual "dress code" for a Vegas steakhouse? Normally, I go around in a polo shirt, khakis, and cross-trainers, but something tells me that's a little underdressed for most steak places that suggest "business casual", but is a suit and tie overkill? How "casual" can I take it without sticking out like a sore thumb?
(I'm not interested in the really upscale places (e.g. SW at the Wynn) - I'm targeting something along the lines of the Pullman at Main Street Station, The Steakhouse at TI, or The Strip House at Planet Hollywood.
