I <3 Burger Bar at Mandalay Palace! I'm not sure if they do groups, but it would be great for picky eaters and burger lovers alike as you are able to select everything - your patty, bun, toppings, sides, etc! The burgers are delish!
I just realized I haven't added myself to this list! FH and I are getting married at the Wynn on August 19, 2009 and having our reception at Boa in the Forum Shops @ Caesars. Our guest list is around 76 but we're expecting about 65 to come party with us!
Looking forward to chatting with the other Vegas brides soon!
STDs are not necessary as long as you provide your guests with enough notice of your wedding date. We told our guests individually when and where we are having our wedding and we have a wedding website to remind them, but we are also having a smallish wedding. I think your guests will understand why they are getting your invite early.
