I would say that's a good budget. You can go to allearsnet.com and get an idea of the menu and cost. The portions are pretty big, so you could split meals.
Do you have a Safari membership? If not, it costs $15.00 and you get
* next available seating
* either 10% off food (and merchandise) or a free appetizer
* they will mail you a $10.00 gift certificate (and then a $5 one for your birthday)
If you have a RFC near you or are planning on going back within the year, it's a good thing to have. You can only sign up at the restaurant though.
ETA: you can use the Safari club card at other Laundry restaurants.
