You live in New York City. There must be a few vapor shops in the area that offer sampling of their flavors before you chose which one you like best. This is the best way to find flavors. The worst mistake is to pick flavors for another person.
Good Guy Vapes in Clifton, NJ (just a few miles from Manhattan) has an awesome juice sample bar. They have their own house juices, but also carry juices from some awesome manufacturers: The Standard Vape, Jameson's, The Vapor Chef, Suicide Bunnies, DB Liquids, NicQuid, and Five Pawns.
Every flavor they carry is available to sample. They have some eGo Twist or Vision Spinner batteries (not sure which, never used theirs because I have my own gear to test with), and load the samples into clearomizers (mostly Evods, but some are CE4's and the like). If you have a dripper, you can also use that -- they'll hand you the bottle and you can drip onto your 510 dripping atomizer or your RDA.
They have a wide range of PV's, from the basic eGos to APV's like the iTaste MVP 2.0, iTaste VV 3.0, eVic, (I think they have it) a Vamo, all the way to a wide variety of mechanical mods.
The MVP 2.0 is an awesome APV, but if it is a bit too large for them, the iTaste VV 3.0 is the same hardware in a smaller package, with a smaller 800 mAh battery and no USB power output.
They also have a good selection of clearomizers, from basic Evods and CE4's to Protanks. Plenty of RBA's and RDA's as well.
Their site is
http://www.goodguyvapes.com. Don't be disappointed if you see that a lot of products are listed as out of stock on their website. They haven't updated in a while -- I was just there today and they had most, if not all, of what's listed on their site, and also have many products that aren't even listed on their site at all.
If you have any questions or would like me to check if they have a particular product in stock, I hope to head back up again tomorrow (Friday 12/20).
(No, I am not affilated with Good Guy Vapes in any way, I'm just a very happy customer of theirs. The staff is friendly and polite, and are very knowledgable and will help steer you in the right direction on what would be best for you. I highly recommend them.)

Their house juice is really good for a house juice. My favorite is The Vapor Chef. They have some incredible flavors, and at $10 for a 15 mL bottle it's an amazing value. The higher-end stuff is also great (Jameson's Peaches and Cream is heavenly). They can get pricey, but are great if you want to splurge. When I stock on on juice from them, I'll usually get five 10 mL bottles of their house juice (to get the free bottle after you buy four), 2 - 3 bottles from The Vapor Chef, 1 - 2 bottles of DB liquids, and possibly (if I have enough cash at the time) one bottle from one of their priciest manufacturers.
And if you live in the city and don't have a car, I'd be happy to give you a ride if you take a train into New Jersey. NJ Transit Main Line to Clifton -- you can take the PATH to Hoboken and get onto a Main Line train directly, or take a NJ Transit train from Penn Station to Secaucus and transfer to a Main Line train there. I could take you from Secaucus but that is a bit out of my way.
