If you do actually want to like it, be sure that you have tried a place that offers Fever Tree tonic and Hendrick's gin and ask for them by name. Do not simply ask for a generic "gin and tonic" made with their cheapest gin and tonic syrup mixed up in their soda dispenser — either of which are quite liable to render the concoction entirely undrinkable.

A good gin and tonic also includes a lime wedge. Even a little of this in the drink makes a big difference.

(Yes, there are definitely other gins that would work, and indeed, other tonics — but these are the more popular big names which you will have more luck finding at bars.)
