TLDR: Naina's has the best burgers I've ever had the pleasure of eating.
Niana's Kitchen is a tiny little restaurant just off of blackfoot trail kitty corner to the Crossroads Farmers Market. You could drive by it a thousand times and never give it the time of day because it's in the little crap strip mall in an industrial area that looks half closed down. If you continue to drive by it however, you'll be missing out on something wonderful.
My first visit, I got I believe the Mediterranean stuffed burger. Anyway, it was stuffed with bacon, goat cheese and other amazing and wonderful things. When I saw it was a stuffed burger, I figured I might get a bit of the flavor of the stuffings, however when you bite into that burger, it's bursting with flavor! There was goat cheese in almost every bite and I was in absolute heaven.
I was also really impressed with the fries. I'm perpetually bored with fries, even from places that have amazing food. The fries at Naina's are seasoned wonderfully. They were cooked perfectly and a bit spicy. I actually enjoyed eating them.
I found Naina's about a week ago, and I've returned 3 times since. I highly recommend it.
