I go in every so often with my sister (but not too often or I'd be around 200 lbs) and we try all the popcorn. Then they offer popcorn that they don't have out in the sample containers. The staff is ridiculously friendly and helpful.
I am currently inhaling the Cupcake popcorn with my sister and have to resist eating the whole bag at once. Though $6.80 may seem expensive for popcorn, this popcorn is worth more. (Not too much more though because then I'd be happy but broke.
