Location is good - Eastern & Serene, not too far from my house. Also, it's near some other places you might be hanging out at (Laziza, Republic, BJs, Pin Kaow).
The atmosphere inside is ok - minimalist for sure, as others have noted.
Lots of samples! Yes!
The flavors are all totally interesting, like Marilyn Monroe, Smores, Caramel Apple, White Cheddar, Salt n' Vinegar, a bunch of others that I forget. I sampled about 4 or 5 and settled on the S'mores. It was delicious.
The owner was in there and gave me a sample of some of the nitrogen-ed corn. It was kinda interesting, but all it does is make your popcorn cold and smoke comes out of your nose/mouth. Not really worth the extra $1.50, unless you're with some kids.
The server and the owner were really helpful and friendly.
Prices...not sure what to say. It is a little high for a thing of popcorn ($5 for a styrofoam cup that's way smaller than anything you get at the movies), but then it is not just plain buttered popcorn. Also, the small cup is only about $3 or $3.50, which is the same or less than what I would spend for a little treat at Red Mango next door.
Plus one point for being locally owned and totally unique to the area.
Overall, I will definitely be back to Popped whenever I'm in the mood for a little snack that's not ice cream/yogurt.
