'true love' is a usual term so, I go with "real love"... in which case anyway, it just a clever advertisement gimmick. here, we have a common tag line for a brand of beer: "real strong, for real men!" ('strong' pertains to the alcohol content of the beer). :)

To me "real love" sounds more modern, hip, youthful and less book-ish and elevated.

Hi it is cool I think...

"Real love" generally pertains to the quality of the love (as opposed to, say, fake love, like physical attraction, loving someone for their money, etc). "True love" is half-idomatic, and used almost exclusively to indicate the measure of love between two people, in the sense of having found the right one. For instance, when you see a couple sitting on a bench, all lovey-dovey, you'd say: "It's true love!" Or, "I found my true love!"

since it is a name of a bar .i think "real love"is better...
