Yes - use Ammo on its own until things are turning very sexual.
A bar/club environment is an ideal place to use Ammo and it will make some kind of impression on most of the folk you meet there but you need to work it - Don’t stay up on the riser behind your kit!
Get yourself out there and meet/talk to people. Follow-up the phero signals with behaviour that justifies the attraction. Look for all sorts of signs of interest. Eye contact mainly but there are other forms of behaviour and body language that signal interest. Have a look through this thread for some ideas on the range you may see.
Mainly, just get out there, be yourself and enjoy it. Don’t neglect your main target of course but equally, don’t be entirely at her beck & call. See she has to earn your interest/attention. 
And if my past experience of Dublin is anything to go by, you will never be far away from attractive and interested women. Its a very sociable place!
