Rocket Fizz is just an amazing place to walk into. I'm a Henderson resident, and I find myself now trying to plot trips out to Summerlin just so I can browse some sodas, buy a bottle or two, and try something different. Their selection is amazing, and at $2 a bottle reasonably priced for a specialty shop. I've seen plenty of Coke machines sell for over that price. My favorite soda so far is the store brand green apple jalapeno. Drink slowly, burping with this is painful as I discovered!
Their candy selection is also pretty impressive, but I have not partaken in that part of the store. The staff is wonderful, especially during the sampling time when I walked in.
Just a unique store that is a pleasure to browse before a movie.
