My standard order in a pub is a pint of lime & soda. Also works well with spicy food, replacing beer (which I havent drunk for many years).
The problem, which I see you share, is that most non alcoholic drinks are sweet and it is not want I want if I’m going to be in a bar for any length of time. I may sip a tonic instead. A good cocktail bar should be able to offer a range of drinks - see if they can make a “virgin mojito” - all the base flavour notes but no booze. I like it.
