For a Mongolian grill, Flat Top is near the top of the price range. Seating is also pretty limited, I've had to wait up near 30 minutes before getting a table. I thought they had a pretty good spread as far as veggies and meat; it's supposed to mimic the main staples in asain cuisine, not be the typical fat American all-you-can-eat buffet. (i.e.: deep fried everything)
I'd recommend this as a very healthy alternative to most restaurants, just hope you don't wait as long as I did....
