I spent a day and a half at the National Museum of the USAF, then went back and spent another two days. If you are going to spend only one day, check their web site first so you don't miss something. Although if you make Dayton an annual event, you can go back to the museum each year also. When I was there, they had just received the Hexagon KH-9 spy satellite, so there is always something arriving.
As I'm sure that you know from personal experience by now, you can have as much or as little as you wish of EVERYTHING. The philosophy of churrascaria is no concept of too much. YOU control the serving by means of a disc with RED on one side, GREEN on the other. Green means feed me, red means no more (for now; you can flip back to green anytime.
@mhrackin: They're about the top of the food chain price-wise but excellent food. Hope you're REALLY hungry!
I am REALLY hungry ... now (armed with your info), I'm hoping that someone else picks up the bill LOL
PS I've been looking at their online menu -- I'm drooling over my keyboad -- I hope you can get smaller portions of multiple types of meat, because I'm soooo tempted by the picahna, cordeiro, and linguica (to name but a few)!
