Found out about Stir Fry Paradise by searching Yelp for Mongolian BBQ restaurants, and what a nice find it was. We called ahead of time to get some general info, mostly because we weren't sure if we wanted to-go or dine in. Over the phone the lady was extremely courteous and helpful. The meal is $7.30 all you can eat (we only had a single plate each with a moderate portion). The to-go price is 35 cents per ounce.
The atmosphere is what you would expect from a typical strip mall restaurant. Not a whole lot of ambiance, but it was very clean. I double-checked the maricopa county health site, and they get predominantly Gold ratings.
The staff was extremely helpful. The hostess followed us to the line explaining how Mongolian BBQ works. We were already familiar with the process, but she made sure we were comfortable with everything anyway.
I think what I liked best about Stir Fry Paradise were the sauces/seasonings. The meats and veggies are pretty much consistent with most Mongolian BBQ places. The only real difference is that I thought the sauces were more flavorful. The other thing I really liked was the shape of the plate. The plate is large with a handle. It was easy to transport and dispersed the heat more quickly than the usual bowls.
We each only had the one serving, and neither one of us finished the plate. There were a couple of beefy-sized families that were just tearing up both sides of the grill. It's fun to people watch at all you can eat places. They were already into seconds before we finished our plate, and there were no signs of them slowing down! In addition to the Mongolian Grill, there is a serving area with rice, chicken wings, bbq beef, and orange chicken (might have been sesame chicken). Not sure because the Mongolian BBQ was already more food than I could hope to eat. They also had jello and sugared donuts on the line - didn't have those either, but the donuts sure looked good.
I give Stir Fry Paradise 5 Stars since the staff was so nice, the food great, and it's a heck of a lot closer than YC's in Scottsdale! Not crazy about AJ's at Metro center.
